gnome-language-selector crashed with ValueError in _build_localename(): too many values to unpack

Status changed to 'Confirmed' because the bug affects multiple users.

Thanks for your help to improve Ubuntu by reporting this bug!

I'm able to reproduce it. I could also make the bug disappear by downgrading python-gi, python-gi-cairo and python-gobject from 3.0.3-1 to 3.0.2-4, so it seems to be caused by the latest pygobject upgrade.

same problem occurs in Oneiric too

Same problem also in 32 bit Xubuntu 12.04

This _exact_ problem should only affect Precise. If you see something similar in Oneiric, can you please submit a separate bug about it.

This issue was introduced by the _decode_value() function in pygobject/gi/overrides/Gtk.py. Assuming that there is a good reason for that function, I propose a python2.7 patch that fixes the issue.

The attachment "locale-as-unicode.diff" of this bug report has been identified as being a patch. The ubuntu-reviewers team has been subscribed to the bug report so that they can review the patch. In the event that this is in fact not a patch you can resolve this situation by removing the tag 'patch' from the bug report and editing the attachment so that it is not flagged as a patch. Additionally, if you are member of the ubuntu-reviewers team please also unsubscribe the team from this bug report.

Easily reproducible python2.7 bug:

$ python -c "import locale; locale.setlocale(locale.LC_ALL, u'de_DE.UTF-8')"
Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "/usr/lib/python2.7/locale.py", line 538, in setlocale
    locale = normalize(_build_localename(locale))
  File "/usr/lib/python2.7/locale.py", line 445, in _build_localename
    language, encoding = localetuple
ValueError: too many values to unpack

Python 3 is not affected. I'll forward this to upstream and add a workaround to language-selector.

The upstream bug says it's not meant to work with unicode, and they updated the documentation instead. So setting the ubuntu task to wontfix, too.

This bug was fixed in the package language-selector - 0.60

---------------
language-selector (0.60) precise; urgency=low

  [ Martin Pitt ]
  * debian/control: Move from transitional python-gobject to python-gi.
  * Drop fontconfig/69-language-selector-ko-kr.conf: Obsolete now with the
    move to fonts-nanum.
  * LanguageSelector/gtk/GtkLanguageSelector.py: Work around python2.7 crash
    when passing an unicode value to setlocale(). (LP: #905429)

  [ Jinkyu Yi ]
  * data/pkg_depends: Add fonts-nanum*.
