Comment 3 for bug 386029

If I set LANG=C in /etc/default/locale, I get a lang-sel crash:
/usr/lib/python2.6/dist-packages/LanguageSelector/gtk/GtkLanguageSelector.py:839: GtkWarning: gtk_cell_view_set_cell_data: assertion `cell_view->priv->displayed_row != NULL' failed
  cell = combo.get_child().get_cell_renderers()[0]
