Qt Version: 4.7.0
Operating System: Linux 2.6.35-27-generic i686
Distribution: Ubuntu 10.10

-- Information about the crash:
- What I was doing when the application crashed: I just double-clic on "Locale" in System Settings, because i wanted to change language settings.
It happens every time I try.
