Package: gnome-control-center
Version: 1:3.29.90-1
Severity: important
Dear Maintainer,
gnome-control-center does not start since 1:3.29.90-1. The error I get:
foo@bar:~$ gnome-control-center -v
17:47:38.0368 sharing-cc-panel: DEBUG: Error calling GetHostNameFqdn: DBus.Error:org.freedesktop.DBus.Error.ServiceUnknown: The name org.freedesktop.Avahi was not provided by any .service files

* What led up to the situation?
I updated gnome-control-center from 1:3.28.2-1 to 1:3.29.90-1
* What exactly did you do (or not do) that was effective (or ineffective)?
I looked up what package provides the missing "org.freedesktop.Avahi" .service file on the package files search site.

I installed avahi-daemon (0.7-4) and gnome-control-center works now
Please consider adding avahi-daemon as a dependency to gnome-control-center or one of its dependencies, whatever makes more sense.
Thank you for your work.

We can fix this, but you would not have been affected by this bug if
you installed recommended dependencies. gnome-control-center
recommends gnome-user-share which depends on libapache2-mod-dnssd
which depends on avahi-daemon.
Please don't disable installing recommends and please take a look at
the list of recommended packages below that you don't have installed.
You are missing out on important gnome-control-center features.

I disabled recommended packages on purpose because it often pulls hundreds of megabytes of dependencies I don't need and never use.
In this case avahi-daemon or libapache2-mod-dnssd should be a dependency and not a recommendation through gnome-user-share or gnome-user-share itself should be a dependency.
According to the "Debian Policy Manual - 7.2. Binary Dependencies" 'depends' "declares an absolute dependency" and 'recommends' "declares a strong, but not absolute, dependency". I think working or not working is kinda the definition of "absolute dependency". A package should work with its dependencies installed and then may provide additional functionality through 'Recommends' and 'Suggests'. This understanding of the meaning of 'depends' and 'recommends' made me report this bug.
It is also very possible that I misunderstand the wording in the Policy Manual :)
Again, thank you very much for your work!

will fix it.
And I give you a "strong, but not absolute" recommendation to not
disable installing recommended packages. :)

Yes it should. I assume a Speicherzugriffsfehler is a segmentation
fault or an assertion failure or something? If so, then that's
gnome-control-center crashing, which it shouldn't be doing even if
avahi-daemon is missing or broken (and ideally even if avahi-daemon is
intended to be a hard dependency, which I suspect it isn't).

g_assert (valid);
but perhaps the wifi panel doesn't always appear?
This does not seem to be the same crash as #906750 - installing
avahi-daemon, or installing gnome-core and all of gnome-control-center's
Recommends, does not fix it.

Please try to repeat this crash (remove avahi-daemon) with an English
locale (LC_ALL=C.UTF-8), and get a backtrace:
https://wiki.debian.org/HowToGetABacktrace
I couldn't reproduce this crash myself on a minimal virtual machine,
because I get a different crash instead, which is not fixed by installing
avahi-daemon (I've opened a separate bug). On my (non-minimal) laptop,
I couldn't trigger this crash by removing avahi-daemon.
It might also help to set the environment variable G_MESSAGES_DEBUG=all
before running gnome-control-center: this would result in more messages
being printed.

This is because I was starting it from outside a GNOME session (to try
to reproduce a crash that happens when Recommends were not installed, I
launched it in openbox or from a ssh session), and it respects OnlyShowIn
when deciding which panels to show. If the desktop environment is neither
GNOME nor Unity, then it doesn't show any, but then (in the experimental
version) manipulating the visibility of the wifi panel assumes that panel
is available and causes a crash.
The version in unstable doesn't crash, but it also doesn't show any
panels.
Mitigation: the menu entry for gnome-control-center itself won't show
in a non-GNOME session either (due to its use of OnlyShowIn), so this
is not something that is really supported or meant to work.
A possible workaround would be: if any panels would be shown on the
current desktop environment, proceed with that subset of panels, but if
no panels would be shown, show all of them (or those that would show in
a GNOME session) instead.

to reproduce a crash that happens when Recommends were not installed, I
launched it in openbox or from a ssh session), and it respects OnlyShowIn
when deciding which panels to show. If the desktop environment is neither
GNOME nor Unity, then it doesn't show any, but then (in the experimental
version) manipulating the visibility of the wifi panel assumes that panel
is available and causes a crash.
The version in unstable doesn't crash, but it also doesn't show any
panels.

anymore and gnome-control-senter starts up fine. Selecting "Sharing" crashes
gnome-control-center and the bug happens again.
Using an englisch locale does not help, the "error word" is still german, but
"Speicherzugriffsfehler" means "segmentation fault".
Using G_MESSAGES_DEBUG=all gives me a better description:
foo@bar:~$ G_MESSAGES_DEBUG=all gnome-control-center -v

Speicherzugriffsfehler
'Freigabe' means 'Sharing'
I don't know where I can get the package with debugging symbols for gnome-control-center.
gdb just shows "Reading symbols from gnome-control-center...(no debugging symbols found)...done."
and there is no gnome-control-center-dbg package (or any gnome related package)
At least there is some more info with G_MESSAGES_DEBUG=all, so this may help a little.
Thank you for your time and work.

Perhaps your most recently-selected panel before the original crash

was Sharing, so g-c-c was reselecting it automatically?
Thanks, I'll try again to reproduce the crash with this new information.

https://wiki.debian.org/HowToGetABacktrace#Installing_the_debugging_symbols
(Normal Debian mirrors don't carry most debug symbols any more, since
they're large and rarely-accessed.)

Package: gnome-control-center
Version: 1:3.30.2-1
Followup-For: Bug #906799
Dear Maintainer,
* What led up to the situation?
Upgrading the system
* What outcome did you expect instead?
Working gnome-control-center
I can reproduce this bug in the current Debian/testing. gnome-control-center
fails to load as root and as normal user.
Error running as root:
g6# gnome-control-center
**
Error running as user:
(gst-plugin-scanner:18923): GLib-GObject-WARNING **: 11:52:38.153: cannot

(gst-plugin-scanner:18923): GLib-CRITICAL **: 11:52:38.154: g_once_init_leave:
assertion 'result != 0' failed
..and so on.
I assume it has to issue with gstreamer somehow. I already deinstalled the old
gstreamer 0.10 leftovers but it did not resolve the problem.
Inside a gnome-session gnome-control-center also won't load. I have tested this
with GNOME session and Enlightenment 0.22 from Debian/testing.
To this message I have attached a small screencast to illustrate the problem.
Thank you kindly for your reply.
Yours Sincerely,
Adrian Immanuel Kiess
