I can confirm this issue when I run some of my projects on intrepid,
examples are the 5-a-day applet [0] and a developing branch of leonov
[1]. I can also confirm that the same code works on hardy and removing
enter/leave thread "fixes" this issue.

I'm sorry, please ignore my last comment, after some more testing &
coding gtk.gdk.threads_enter()/gtk.gdk.threads_leave() is working
correctly for me.

Please see the attachment for a minimal example on how I'm using
threading in pygtk now, which is working on intrepid.

Ubuntu 8.10, pida 0.5.1-5. On starting it you get the small gray window
appear in the centre of the screen, but it stays empty; the "love"
message doesn't appear. Nothing ever happens. Closing the window using
the menu on the panel icon results in "it's not responding, force quit"
which can kill it.

strace suggests it's getting stuck on futex(2). I suspect a race
condition as one of the attempts to start it, identical to all the
others, succeeded.

Note, a separate issue is choosing Emacs for the embedded editor without
having Emacs installed. Then it just stops with "[Errno 2] No such file
or directory" because a child process tried
"execve("/usr/local/sbin/emacs", ["emacs", "--parent-id", "81789128",
"-f", "server-start", "-l", "/home/peter/.pida2/pida_emacs_in"...], [/*
22 vars */]) = -1 ENOENT" for every directory in PATH.

Ubuntu 9.04 jaunty (updated from hardy, not a fresh install)

$ LANG=C apt-cache policy pida
pida:
Installed: 0.5.1-5ubuntu1
Candidate: 0.5.1-5ubuntu1
Version table:
*** 0.5.1-5ubuntu1 0
500 http://it.archive.ubuntu.com jaunty/universe Packages
100 /var/lib/dpkg/status

starting pida from my account, it hangs as described by Ralph Corderoy, even if I remove pida config dir (~/.pida2)
Today I created a new user account and I can run pida without problems.

thats something i can't debug - i'd apreciate more informations

[JC Hulce]

The version of this program in Ubuntu has been updated and this bug may
have been fixed. Can you still reproduce it?
