User problem accessing tickets.

[Roger Oberholtzer]

I have a single Trac user who cannot access tickets. I do not think it
is their local computer or browser that is the problem: It does not
make any difference what browser/system they try from. Other users can
use this user's browser to log in to their own accounts okay. This
user also cannot access Tickets from another computer's browser. It
seems to be user-specific.

In the Admin->permissions tab, this user looks the same as all other users.

What happens is that when they log in (apache authorization), they get
a box in the initial wiki page that says:

Warning: Error with navigation contributor "TicketModule"

Trac is there with all menus and such, and they can do everything
except access tickets. If they try to do so, they get this error (in
an Oops... page):

UnidecodeDecodeError: 'utf8' codec can't decode byte 0xd2 in position
152: invalid continuation byte.


This is only for this user.

I am running Trac 1.0.2. There have been no changes to any part of the
system. And it is only for one user.

I am not certain where to continue. If it was for everyone or all at a
specific browser, I might have a clue. But only one user no matter
where he logs in from.

Any ideas?

I had a similar problem, only experienced by a single user, due to BookmarksPlugin. The user had bookmarked a resource that was causing a traceback, but no other users had bookmarked the resource.

Which plugins do you have installed? Are you running AgiloForTrac?

Can you find a full traceback in the logs?

No Bookmarks or Agilo plugins. But the user may be watching a ticket.

As to the log, it is kind of hard to tell, but I think this looks like
it could be from when this happens:

Which language has the user chosen?  What is your babel version?

All the menus and such are shown in English. Same for all the users
for which this seems to be working. O part of Trac or any installed
software has been modified from when this worked.

I'm unsure if Babel 1.3 works well with Trac 1.0.2. You could try upgrading Trac, downgrading Babel to 0.9.6, or removing Babel if you don't need internationalization.

I can try that. But I am unsure why this effects one user who is not
using localized messages.

In fact, I want to upgrade Trac and all components to a newer version.
On this machine I have been using packages from openSUSE. They are no
longer making packages for this version of openSUSE. So I will have to
upgrade by hand. That is no problem as that is how I originally did
this. It has been on my to-do list...

I don't have an explanation, but I would check the user's language preference setting. Is it set explicitly to //English (United States)// or //Default language//? Could it possibly be set to //English (United Kingdom)//?

Follow up: problem 'solved'.

I looked through the Trac database for anything that looked different for what turned out to be two users. I could find nothing.

So, ooc, I logged in as these users from my browser. All worked for me. Here is the mysterious part: after that all works for them as well.

So logging in from a different computer seems to have cleared something. Note that using a different browser on the same computer did not help.

Maybe it is related to the browser language setting and the
Accept-Language HTTP header [1]_ [3]_ . If you could inspect requests
, e.g. with a tool like Fiddler [1]_ , you could see the data the
browser is sending on the wire (though I guess there should be
something in the logs with the appropriate log/level set ... DEBUG? )
