Comment 15 for bug 425202

Patch '425202-PythonGettext-v2.diff' tested with command line version (r11552) on OS X 10.7.4 [1]:
Error messages returned from extensions script are not translated (tested with LANG="fr_FR.UTF-8" and running the extension 'Perspective' with two circles selected).

[1] will test with packaged version later: at the moment, the patch does not consider osx packaging yet (platform: darwin).
With the osx-packaged version, the environment variable is set in the launcher script inside the relocatable application bundle (not in 'src/main.cpp'):
