Application: kxkb (2.0)
KDE Platform Version: 4.4.2 (KDE 4.4.2)
Qt Version: 4.6.2
Operating System: Linux 2.6.32-22-generic x86_64
Distribution: Ubuntu 10.04 LTS

-- Information about the crash:
Usually Kxkb just "loose" settings for other language beside English. So if I will click on Kxkb icon in traybar - I see only Engllish (normally I have English and Russian). I am fixing this by clicking "Configure" in tray icon menu, de-selecting and selecting back "Enabe keyboard layouts" and click "Apply".

This type of crash happens silently usually and I really have no clue what happens at this moment. It can just sit for a while and I suddenly notice that I am unable to switch language.

Today Kxkb actually crashed with segmentation fault - just like usual - but this time with segmentation fault exception. I am not sure if this segmentation fault connected to "crash" described above, but hope so =)

The crash can be reproduced every time.
