Thanks for making this bug public, Jean-Baptiste. It's kind of annoying when a large number of bugs are automatically made duplicates of a private bug.

When was the fix released? Because this is still an issue for me.

@Daryl
It was uploaded yesterday at 20.00 UTC. If it's still an issue with v. 0.49, please let us know.

I just had this bug with v 0.49. See #833785 .

@Philipp
That's strange. I can't reproduce it, and the bug reports have stopped dropping in. Also, Traceback.txt in bug 833785 indicates that it's v. 0.48.

Are you able to reproduce the bug, or was it a temporary thing?

In addition to bug #833785, another contradictory report - bug #838019 - has been marked as a duplicate of this bug. On one hand it states package language-selector-common 0.49, but on the other hand the attached Traceback.txt indicates something else:

Traceback (most recent call last):
  File "/usr/bin/fontconfig-voodoo", line 102, in <module>
    main()
  File "/usr/bin/fontconfig-voodoo", line 88, in main
    fc.setConfigBasedOnLocale()
  File "/usr/lib/python2.7/dist-packages/LanguageSelector/FontConfig.py", line 114, in setConfigBasedOnLocale
    lang = self.li.getUserDefaultLanguage()[1]
  File "/usr/lib/python2.7/dist-packages/LanguageSelector/LocaleInfo.py", line 251, in getUserDefaultLanguage
    warnings.warn(msg)
------------------^^^
This tells me that the 0.48 version of LocaleInfo.py was used, not version 0.49.

@Philipp Dreimann and Edson T. Marques,
It would be great if you could let us know if the problem persists also after a reboot, or if it was a temporary glitch.

The problem seems to be solved.

Thanks!

Thanks for letting us know, Philipp. However, two more bugs besides yours (bug #839212 and bug #838019) report about the same type of mysterious crash.

I'm confused. :( Subscribed Martin Pitt for help on this.

bug 839212 is a dupe with language-selector 0.50 so reopening this task.

It seems like dpkg does not safely replace the old LocaleInfo.py file with the new one when upgrading to 0.49 or 0.50. I'm not able to tell if that is a general dpkg problem, or if the reason can be found in the language-selector package.

I'm closing this again as the tracebacks clearly indicate that the crash happened with a version earlier than 0.49. I suppose what happened is that the crash happened, then people dist-upgraded, and only the reported the crash, so apport picked up the wrong package version.

If you can still reproduce this with the current versions, please shout here. Thanks!
