            Bug ID: 348272
           Summary: kwin_x11 crashes on start-up
           Product: kde
           Version: unspecified
          Platform: unspecified
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: unassigned-bugs at kde.org
          Reporter: rewarp at thestrayworld.com

Application: kwin_x11 (5.3.1)

Qt Version: 5.4.1
Operating System: Linux 3.16.7-21-desktop x86_64
Distribution: "openSUSE 13.2 (Harlequin) (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:
Booting up computer.

- Unusual behavior I noticed:
Before the update and restart, switching activities with the shortcut key
causes parts of the desktop to freeze, with the exception of KRunner and
applications. Panel did not respond to mouse input, yet applications could run.

The crash can be reproduced every time.

-- Backtrace:
Application: KWin (kwin_x11), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
