Application: plasma-desktop (0.3) KDE Platform Version: 4.5.1 (KDE 4.5.1) (Compiled from sources) Qt Version: 4.6.3 Operating System: Linux 2.6.35-gentoo-r7 x86_64 Distribution (Platform): Gentoo Packages -- Information about the crash: - What I was doing when the application crashed: Attached an external monitor, went to systemsettings->Display&Monitor->Activated VGA1->Hit "Apply" The second monitor got activated and plasma crashed. I have read a lot of Bug reports the assistant showed me, but all that looked like related have either been marked as duplicates of bugs which described something completely differen (like using plasmoids/show dashboard) or were marked as FIXED in 4.3, 4.4, 4.5, or newer QT. But with KDE-4.5.1 and QT-4.6.3, according to these reports, this crash shouldn't happen any more. -- Backtrace: Application: Plasma-Arbeitsfläche (kdeinit4), signal: Segmentation fault [KCrash Handler] #6 0x00007fe6a206d290 in QWidget::mapToParent(QPoint const&) const () from /usr/lib64/qt4/libQtGui.so.4 #7 0x00007fe6a206d2eb in QWidget::mapTo(QWidget*, QPoint const&) const () from /usr/lib64/qt4/libQtGui.so.4 #8 0x00007fe6876c09ba in SystemTray::X11EmbedPainter::performUpdates() () from /usr/lib64/kde4/plasma_applet_systemtray.so #9 0x00007fe6876c1008 in SystemTray::X11EmbedPainter::qt_metacall(QMetaObject::Call, int, void**) () from /usr/lib64/kde4/plasma_applet_systemtray.so #10 0x00007fe6a2e9b4e6 in QMetaObject::activate(QObject*, QMetaObject const*, int, void**) () from /usr/lib64/qt4/libQtCore.so.4 #11 0x00007fe6a2e97d23 in QObject::event(QEvent*) () from /usr/lib64/qt4/libQtCore.so.4 #12 0x00007fe6a20248dc in QApplicationPrivate::notify_helper(QObject*, QEvent*) () from /usr/lib64/qt4/libQtGui.so.4 #13 0x00007fe6a202ae2b in QApplication::notify(QObject*, QEvent*) () from /usr/lib64/qt4/libQtGui.so.4 #14 0x00007fe6a3bde816 in KApplication::notify(QObject*, QEvent*) () from /usr/lib/libkdeui.so.5 #15 0x00007fe6a2e8831b in QCoreApplication::notifyInternal(QObject*, QEvent*) () from /usr/lib64/qt4/libQtCore.so.4 #16 0x00007fe6a2eb4d42 in QTimerInfoList::activateTimers() () from /usr/lib64/qt4/libQtCore.so.4 #17 0x00007fe6a2eb1b54 in timerSourceDispatch(_GSource*, int (*)(void*), void*) () from /usr/lib64/qt4/libQtCore.so.4 #18 0x00007fe69e59bc31 in g_main_context_dispatch () from /usr/lib/libglib-2.0.so.0 #19 0x00007fe69e59fa88 in g_main_context_iterate () from /usr/lib/libglib-2.0.so.0 #20 0x00007fe69e59fc3c in g_main_context_iteration () from /usr/lib/libglib-2.0.so.0 #21 0x00007fe6a2eb1843 in QEventDispatcherGlib::processEvents(QFlags<QEventLoop::ProcessEventsFlag>) () from /usr/lib64/qt4/libQtCore.so.4 #22 0x00007fe6a20d367e in QGuiEventDispatcherGlib::processEvents(QFlags<QEventLoop::ProcessEventsFlag>) () from /usr/lib64/qt4/libQtGui.so.4 #23 0x00007fe6a2e86c72 in QEventLoop::processEvents(QFlags<QEventLoop::ProcessEventsFlag>) () from /usr/lib64/qt4/libQtCore.so.4 #24 0x00007fe6a2e87044 in QEventLoop::exec(QFlags<QEventLoop::ProcessEventsFlag>) () from /usr/lib64/qt4/libQtCore.so.4 #25 0x00007fe6a2e8bcbb in QCoreApplication::exec() () from /usr/lib64/qt4/libQtCore.so.4 #26 0x00007fe696033586 in kdemain () from /usr/lib64/libkdeinit4_plasma-desktop.so #27 0x0000000000407523 in launch(int, char const*, char const*, char const*, int, char const*, bool, char const*, bool, char const*) () #28 0x00000000004080a0 in handle_launcher_request(int, char const*) () #29 0x00000000004085cb in handle_requests(int) () #30 0x00000000004091a1 in main () Possible duplicates by query: bug 249516, bug 248132, bug 245892, bug 243943, bug 239853.

Created attachment 52746 [details] New crash information added by DrKonqi plasma-desktop (0.3) on KDE Platform 4.5.1 (KDE 4.5.1) using Qt 4.7.0 - What I was doing when the application crashed: I'm using "disper" (nvidia graphics card) to switch to a dualscreen setup. With this KDE version, everytime i apply the setup to use the 2nd monitor, Plasma crashes. Laptop screen has resolution of 1920x1200, external monitor to add, has 1600x1200. -- Backtrace (Reduced): #7 QWidget::mapToParent (this=0x0, pos=...) at kernel/qwidget.cpp:4148 #8 0x014dc7db in QWidget::mapTo (this=0x0, parent=0x9e3b110, pos=...) at kernel/qwidget.cpp:4104 #9 0x02f00b46 in SystemTray::X11EmbedPainter::performUpdates (this=0x92c5160) at ../../../../../plasma/generic/applets/systemtray/protocols/fdo/x11embedpainter.cpp:134 #10 0x02f01021 in SystemTray::X11EmbedPainter::qt_metacall (this=0x92c5160, _c=QMetaObject::InvokeMetaMethod, _id=4, _a=0xbfdafb0c) at ./x11embedpainter.moc:75 [...] [...] #13 0x025f5217 in QTimer::timeout (this=0x9e59294) at .moc/release-shared/moc_qtimer.cpp:134
