Application: systemsettings (4.11.3)
KDE Platform Version: 4.11.3
Qt Version: 4.8.6
Operating System: Linux 3.11-1-686-pae i686
Distribution: Debian GNU/Linux unstable (sid)

-- Information about the crash:
- What I was doing when the application crashed:

I wanted to discover which theme is being used for the desktop.

I selected "System Settings" application from the K-start button in the Panel.  The application started normally and the window appeared.

I selected the "Workspace Appearance" icon (under "Workspace Appearance and Behaviour").  The window updated to show four "tabs" on the left side ("Window Decorations"; "Cursor Theme"; "Desktop Theme"; "Splash Screen"), with "Window Decorations" initially selected.

Selecting any of "Window Decorations", "Cursor Theme" or "Splash Screen" worked fine: the window was updated to show the relevant themes.

Selecting "Desktop Theme" triggered the application to crash.

The program always crashed at this point (three times out of three attempts).

The crash can be reproduced every time.
