Cannot reproduce too using r902024
> What styles do you have installed? CDE Cleanlooks Motif Oxygen Plastique QtQurve Windows Phase (Фаза in russian)
Do you experience the crash when only cycling to Oxygen or Plastique (without selecting the other styles) ? Thanks :)
(In reply to comment #5) > Do you experience the crash when only cycling to Oxygen or Plastique (without > selecting the other styles) ? Thanks :) > If I set Oxigen style and then cycling to Oxygen or Plastique (without selecting the other styles) there is no crash. Also there is no crash if I select other styles. But if I select Plastique style and then cycling to Oxygen or Plastique (without selecting the other styles), systemsettings crash with this: Приложение: Системные параметры (systemsettings), сигнал SIGSEGV Thread 1 (Thread 0xb60c26c0 (LWP 8331)): [KCrash Handler] #6 0xb6f3343a in QProgressBar::minimum () from /usr/lib/libQtGui.so.4 #7 0xb74bb53f in QObject::event () from /usr/lib/libQtCore.so.4 #8 0xb6b4e8ec in QApplicationPrivate::notify_helper () from /usr/lib/libQtGui.so.4 #9 0xb6b5672e in QApplication::notify () from /usr/lib/libQtGui.so.4 #10 0xb79fbd3d in KApplication::notify (this=0xbfcfbc34, receiver=0x8a30438, event=0xbfcfb99c) at /build/buildd/kde4libs-4.1.85/kdeui/kernel/kapplication.cpp:307 #11 0xb74abe61 in QCoreApplication::notifyInternal () from /usr/lib/libQtCore.so.4 #12 0xb74d9d81 in ??

(In reply to comment #7) > > Can you install "libqt4-dbg" to get proper debug symbols ? Thanks :) > It's already installed. Maybe something else?

I could reproduce it in KDE trunk + Qt4.5rc1 I reported the crash UPSTREAM as I could create a Qt-only testcase (reduced version of the KDE appearance module) I'm going to post here the bug number of the Trolltech bug tracker when they assign me one. Thanks
