Bug 288356

Application: systemsettings (1.0)
KDE Platform Version: 4.7.2 (4.7.2)
Qt Version: 4.7.3
Operating System: Linux 3.1.0-1-amd64 x86_64
Distribution: Debian GNU/Linux unstable (sid)

-- Information about the crash:
I clicked on "Get New Themes", on System Settings -> Desktop Theme. Then, I received an "Unknown Open Collaboration Service API error. (0)" and no theme entries. After that, when I clicked on "Order by: Rating" (I was just playing with the filters), the app crashed.

The crash can be reproduced every time.

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