Looks like a dupe of 246652. This has started happening to people recently, apparently either in relation to the Qt 4.7 branch or KDE trunk, or both. I haven't been able to reproduce it myself yet, but I'm stuck on Qt 4.7 beta2 at the moment. *** This bug has been marked as a duplicate of bug 246652 ***
Created attachment 53568 [details] New crash information added by DrKonqi yakuake (2.9.7) on KDE Platform 4.5.3 (KDE 4.5.3) using Qt 4.7.0 - What I was doing when the application crashed: Just type "exit" in Yakuake's terminal. This started to happen after last upgrade. This occurs very often but not always. Nearly 90% times. -- Backtrace (Reduced): #7 operator!= (this=0xa2212e0, action=0xa207a80) at ../../include/QtCore/../../src/corelib/thread/qbasicatomic.h:75 #8 detachShared (this=0xa2212e0, action=0xa207a80) at ../../include/QtCore/../../src/corelib/tools/qlist.h:131 #9 removeAll (this=0xa2212e0, action=0xa207a80) at ../../include/QtCore/../../src/corelib/tools/qlist.h:757 #10 QWidget::removeAction (this=0xa2212e0, action=0xa207a80) at kernel/qwidget.cpp:3167 #11 0x0091f3b6 in KActionCollection::removeAssociatedWidget (this=0xa221260, widget=0xa2212e0) at ../../kdeui/actions/kactioncollection.cpp:723
Created attachment 54589 [details] New crash information added by DrKonqi yakuake (2.9.6) on KDE Platform 4.5.3 (KDE 4.5.3) using Qt 4.7.0 - What I was doing when the application crashed: had about 8 or 9 tabs open. Closing them out typing exit from shell (bash) when application crashes. It has happened on a number of occasions and always seems to occur if I am closing them out rapidly in succession. If I close 1 or 2 or close them slowly it doesn't crash. -- Backtrace (Reduced): #6 0x00007fb4b0ce5f79 in QWidget::removeAction(QAction*) () from /usr/lib/libQtGui.so.4 #7 0x00007fb4b24f3dd4 in KActionCollection::removeAssociatedWidget(QWidget*) () from /usr/lib/libkdeui.so.5 #8 0x00007fb4b27083bd in KXMLGUIClient::prepareXMLUnplug(QWidget*) () from /usr/lib/libkdeui.so.5 #9 0x00007fb4b2711046 in KXMLGUIFactory::removeClient(KXMLGUIClient*) () from /usr/lib/libkdeui.so.5 #10 0x00007fb4b270ab51 in KXMLGUIClient::~KXMLGUIClient() () from /usr/lib/libkdeui.so.5
