Bug 326978

Application: systemsettings (4.11.2)
KDE Platform Version: 4.11.2
Qt Version: 4.8.4
Operating System: Linux 3.11.0-12-generic x86_64
Distribution: Ubuntu 13.10

-- Information about the crash:
- What I was doing when the application crashed:
opened systemsettings - locale - languages - selected French and clicked on the right arrow to add it to the preferred languages; entered my password then systemsettings crashed.
This is reproductible and happens also (at least) if I try to add German instead of French (I did not try with other languages).

The crash can be reproduced every time.

-- Backtrace:
Application: System Settings (systemsettings), signal: Segmentation fault
