Bug#668657: wicd-gtk segfaults after clicking tray icon.

April 13th, 2012 - 05:00 pm ET by Pawel Rozanski | Report spam

Package: wicd-gtk
Version: 1.7.2.1-1
Severity: normal

Wicd-gtk runs fine, unless I click on icon in the tray, then crashes. Running on console wicd-gtk causes instant
segfault. Running wicd-gtk -t makes it run, unless tray icon is clicked. I belive locale setting are the problem,
as running LANG=C wicd-gtk or LANG=pl_PL.UTF-8 wicd-gtk solves the problem.

System is stable+testing+unstable. The same problem existed on version 1.7.1-1 from testing.

It may have the same source as bug #640248. Anyway I believe, application shouldn't crash on locale problem.

Debian Release: 6.0.4
APT prefers stable-updates
APT policy: (500, 'stable-updates'), (500, 'stable'), (401, 'testing'), (400, 'unstable'), (100, 'experimental')
Architecture: amd64 (x86_64)

Kernel: Linux 3.2.0-2-amd64 (SMP w/4 CPU cores)
Locale: LANG=pl_PL, LC_CTYPE=pl_PL (charmap=ISO-8859-2)
Shell: /bin/sh linked to /bin/dash

I have an UTF-8 locale (Italian), and can't reproduce this.

Also, it would be nice if you could give some more info, for example the
traceback you get on console.

To reproduce try to run LANG=pl_PL wicd-gtk (no other interaction
required as it opens wicd-gtk in a window - the same thing as clicking
on tray icon does).

Not sure what you mean by traceback. I assume it's console output, so:
$ wicd-gtk
Has notifications support True
Loading...
Connecting to daemon...
Connected.
Naruszenie ochrony pamięci

Last line is segfault message in Polish.

This traceback shows nothing related to wicd.

I'm not sure who this bug belongs to, I'm reassigning it to glib because it was
the last thing called in the traceback.

Glib maintainers: please forgive me if you're not the culprit. Feel free to
reassign to someone else. This is surely *not* a bug in wicd. I retitled the
bug to reflect what I think might be the issue, and I might be totally wrong.
So take the title with a grain of salt :)

Kindly,
David
