Languages not displayed correctly in "language control module": German and English are empty

[Daniel Hahler]

When opening the language control module ("kcmshell4 language"), the names of the languages are displayed by their country code (e.g. "fr" for France/French), but the label names of the entries for English and German are empty.

I am attaching a screenshot, where "German"/"de" is configured as preferred language.

These are the language packs I have installed:
% dpkg -l|grep -P '^ii\s+language-pack' | awk '{print $2}'
language-pack-de
language-pack-de-base
language-pack-en
language-pack-en-base
language-pack-gnome-de
language-pack-gnome-de-base
language-pack-gnome-en
language-pack-gnome-en-base
language-pack-kde-de
language-pack-kde-en

Languages are never supposed to be displayed by their internal code, and the fact that they are is sign of breakage somewhere along the line. I think the package localepurge could cause issues like that.

This bug was fixed in the package localepurge - 0.7.3.2ubuntu1

---------------
localepurge (0.7.3.2ubuntu1) vivid; urgency=medium

  * Keep /usr/share/locale/all_languages from kdelibs5-data. (LP: #1243620)

Thanks for the pointer, Harald.

For reference:
I was not aware that there was a bug already when I've submitted my patch, which was therefore incomplete.
See bug 1255761 for the remaining issues with KDE.
