           Summary: KWin Crashes after Closing 'Special Application
                    Settings' Dialog Box
           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: corey.bobco at gmail.com

Application: kwin_x11 (5.1.2)

Qt Version: 5.3.2
Operating System: Linux 3.16.0-28-generic x86_64
Distribution: Ubuntu Vivid Vervet (development branch)

-- Information about the crash:
Right click on the title bar of an application and select "More Actions' -->
'Special Application Settings.' This will open a dialog box for tweaking KWin
settings. Upon closing this dialog box with the window title bar's top-right X
button, KWin crashes and restarts. 

On Kubuntu alpha with latest packages.

The crash can be reproduced every time.

-- Backtrace:
Application: KWin (kwin_x11), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
