Bug 288626

Application: systemsettings (1.0)
KDE Platform Version: 4.7.3 (4.7.3)
Qt Version: 4.8.0
Operating System: Linux 3.1.2-1.fc16.x86_64 x86_64
Distribution: "Fedora release 16 (Verne)"

-- Information about the crash:
- What I was doing when the application crashed:
Attempting to modify window decorations via System-Settings, Workspace Appearance, Window Decorations (select Oxygen theme), Configure Decoration, Window-specific overrides, and click the add button. This causes a crash in the application.

Attempting to modify Firefox's window decorations, and it happens every time.

The crash can be reproduced every time.

-- Backtrace:
Application: System Settings (systemsettings), signal: Aborted
Using host libthread_db library "/lib64/libthread_db.so.1".
