Description Shubhadeep Chaudhuri 2011-12-01 11:51:25 UTC 
Whenever I try to add an override to oxygen window decoration, systemsettings just crashes instead of opening a new window.

Environment: Gentoo amd64, KDE 4.7.3, Qt 4.8 RC1, GCC 4.6.2

Reproducible: Always

Steps to Reproduce:
 1. Open System Settings
 2. Select "Workspace Appearance"
 3. Select "Configure Decorations" button.
 4. Select "Window-Specific Overrides" tab
 5. Click "+Add" button

Actual Results: 
 System-Settings crashes, and the KDE Crash Handler launches

Expected Results: 
 A window pops up allowing me to choose window-specific override settings.

Backtrace:
Application: System Settings (systemsettings), signal: Aborted

Comment 1 Tsiapaliokas Antonis 2011-12-07 14:01:13 UTC 
Hello

I cannot reproduce this bug on KDE 4.7.3, Qt 4.7.3, GCC 4.5.3-r1. Could you try to reproduce this with Qt 4.7.3?
Comment 2 Shubhadeep Chaudhuri 2011-12-07 19:54:18 UTC 
I reported this upstream & they said this is probably a Qt bug. Unfortunately, no response in the Qt bug report.

This bug is OK to close.

Could you provide the URLs for these bugs?
