            Bug ID: 313187
           Summary: Short freeze followed by kwin_gles
    Classification: Unclassified
           Product: kde
           Version: unspecified
          Hardware: unspecified
                OS: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: unassigned-bugs at kde.org
          Reporter: 0inkane at googlemail.com

Application: kwin_gles (4.9.97)
KDE Platform Version: 4.9.97
Qt Version: 4.8.4
Operating System: Linux 3.6.6-1-CHAKRA x86_64
Distribution: "Chakra"

-- Information about the crash:
- What I was doing when the application crashed:
I tried to switch to a different virtual desktop via a keyboard shortcut.
- Unusual behavior I noticed:
Just before I switched the desktop seemed to be frozen (mouse pointer not
changing, virtual desktop not changing immediately. 

Further notes: Normally I don't have any problem with kwin_gles. I got a
similiar crash (behaviour wise)  with normal kwin once, but unfortunately I
didn't save the backtrace.

-- Backtrace:
Application: KWin (kwin_gles), signal: Segmentation fault
