            Bug ID: 304434
          Severity: crash
           Version: 1.0
          Priority: NOR
          Assignee: unassigned-bugs at kde.org
           Summary: Kwin decoration settings crashes with
                    kwin-style-dekorator installed
    Classification: Unclassified
                OS: Linux
          Reporter: gasinvein at gmail.com
          Hardware: Ubuntu Packages
            Status: UNCONFIRMED
         Component: general
           Product: systemsettings

Application: systemsettings (1.0)
KDE Platform Version: 4.9.00
Qt Version: 4.8.1
Operating System: Linux 3.5.0-7-generic x86_64
Distribution: Ubuntu 12.04 LTS

-- Information about the crash:
- What I was doing when the application crashed:
Clicking "Appearence" in system settings causes kwin decoration settings to
segfault. Without kwin-style-dekorator (0.5.1-1ubuntu1) installed everything is
ok.

- Custom settings of the application:
oxygen-transparent installed

The crash can be reproduced every time.

-- Backtrace:
Application: Параметры системы (systemsettings), signal: Segmentation fault
