Created attachment 66124 [details] Here's the backtrace although I doubt this would be useful Version: 1.0 (using KDE 4.7.3) OS: Linux Whenever I try to add an override to oxygen window decoration, systemsettings just crashes. I can myself confirm this on Fedora 16 x86_64 as well as Gentoo x86_64. Also happens on Fedora 16 x86 according to another person. This bug has probably been present since KDE 4.7.1. 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.
This is also present in KDE 4.7.80
Please rather post than attach backtraces, thanks. Application: System Settings (systemsettings), signal: Aborted Using host libthread_db library "/lib64/libthread_db.so.1".

doesn't crash here btw. (32bit) neither 4.7.3 nor git master
... cannot reproduce here either, using git master and 32Bits, also besides theres is no Oxygen code at all involved in the backtrace, and besides KApplication::notify, no kde code either. I'd suspect a Qt issue (which version is it by the way) or a qt installation issue ... Also, I don't quite understand why there are so many (??) in the log. I can't understand #39 0x0000003d927906ab in ?? () from /usr/lib64/libQtGui.so.4 vs later: #40 0x0000003d9279091c in QAbstractButton::mouseReleaseEvent(QMouseEvent*) () from /usr/lib64/libQtGui.so.4 Are all debug libs installed ? Will keep open for a while in case there is other feedback or more usefull duplicates open, but I believe it is likely upstream and should be reported to Qt.
Ah also: can you reproduce if you try do the same from "oxygen-settings" applications (type it in a terminal or krunner) ?
Well, I am using Qt 4.8 RC1, so I guess you're right about this being a Qt issue. And oxygen-settings still crashes on running from the terminal with error "QSharedPointer: pointer 0xd3a2e0 already has reference counting".

Please report to Qt. (basically, its a FATAL that Qt throws and it should not).
