Application: kcmshell4 (4.11.2)
KDE Platform Version: 4.11.2
Qt Version: 4.8.5
Operating System: Linux 3.11.6-4-desktop i686
Distribution: "openSUSE 13.1 (Bottle) (i586)"

-- Information about the crash:
- What I was doing when the application crashed: Tried opening Audio & Video Settings but everytime I did open it, it crashed leading me to file a bug report.

- Unusual behavior I noticed:Nothing unusual except my Audio is working only when the headphones are plugged in. First I thought if my inbuilt speakers have stopped working but then it works perfectly fine while using Windows 7.

- Custom settings of the application: Not Applicable

The crash can be reproduced every time.

-- Backtrace:
Application: KDE Control Module (kcmshell4), signal: Segmentation fault
