[Bug 891266] Re: systemsettings crashes when add Uzbek (Cyrillic) to Preffered Languages

Thu Nov 17 11:32:21 UTC 2011

When I add Uzbek (Latin) or Russian to Preffered languages systemsettings
doesn't crash. Only when I add Uzbek (Cyrillic) systemsettings crashes. If I
add some more languages (e.g. Russian and Uzbek), systemsettings crashes when I
move Uzbek (Cyrillic) to the top.

Application: systemsettings (1.0)
KDE Platform Version: 4.7.2 (4.7.2)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-13-generic i686
Distribution: Ubuntu 11.10

-- Information about the crash:
- What I was doing when the application crashed: I've installed Russian and
Uzbek lokalization packages. Run System Settings > Locale > Country/Region &
Language > Languages tab. System Settings crashes when try to add Uzbek
(Cyrillic) from Available Languages to Preffered Languages. There is no error
when adding other languages.

The crash can be reproduced every time.
