Bug 328384

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

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

I have been  receiving numerous "notifications" that "KDE would like to remove most, if not all" of my audio devices. Ocassionally, also, all of the audio devices dissappear from the "Preference tables under the KDE audio setup.
I am a member of the "Audio Group".
To re-instate my audio devices, I  changed my audio device preferences giving my ASUS Sound card preference over the inbuilt INTEL internal sound card. 
 Everything seemed to work, as usual, but on re-booting I cannot enter the KDE audio setup.
The System now crashes every time on entering KDE audio setup.

The crash can be reproduced every time.

-- Backtrace:
Application: KDE Control Module (kcmshell4), signal: Segmentation fault
Using host libthread_db library "/lib/libthread_db.so.1".
