            Bug ID: 328384
           Summary: Every time Audio Selected in  "Settings" causes
                    immediate crash
    Classification: Unclassified
           Product: systemsettings
           Version: 4.11.2
          Platform: openSUSE RPMs
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: unassigned-bugs at kde.org
          Reporter: i.peden at ntlworld.com

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".
