screenshot of 'Unknown' languages
LibO_3.3.0rc3_Win_x86_install_all_lang.exe, Tools - Options - Language Settings - Languages
In the User Interface drop-down box there are 3 'Unknown' entries.
I'll investigate it.
The three 'Unknown' languages are:
ms - Malay
ur - Urdu
ps - Pashto
I fixed this by removing ms, ur, ans ps from postset.mk. UI localization does not exist in these languages. So it makes no sense to build anything in these languages. Incidentally this also fixed this bug.
