Created attachment 73010 [details] New crash information added by DrKonqi dolphin (2.0) on KDE Platform 4.8.4 (4.8.4) using Qt 4.8.1 - What I was doing when the application crashed: I opened a Java application from the Kickoff Application Launcher, however, this seems rather irrelevant. That is so because, while the application was opening in the BG, the mouse pointer was hovering over some file (likely to be a media file) icon in the Dolphin browser. I believe it was trying to generate a preview. Additional Information: I have Nepomuk and Strigi turned off. -- Backtrace (Reduced): #7 QCoreApplication::notifyInternal (this=0xbf9b32f8, receiver=0x9827cf8, event=0xbf9b2bec) at kernel/qcoreapplication.cpp:864 #8 0xb58aa79b in sendEvent (event=<optimized out>, receiver=<optimized out>) at ../../include/QtCore/../../src/corelib/kernel/qcoreapplication.h:231 #9 QApplicationPrivate::dispatchEnterLeave (enter=0x9827cf8, leave=0xb623eafc) at kernel/qapplication.cpp:2824 #10 0xb5935a25 in QApplication::x11ProcessEvent (this=0xbf9b32f8, event=0xbf9b2f6c) at kernel/qapplication_x11.cpp:3805 #11 0xb5962eac in x11EventSourceDispatch (s=0x902a950, callback=0, user_data=0x0) at kernel/qguieventdispatcher_glib.cpp:146

Git commit a6f0745284617e3eccd0f69597105771e54aa31b by Frank Reininghaus. Committed on 24/11/2012 at 05:08. Pushed by freininghaus into branch 'KDE/4.9'. Delete FileMetaDataToolTip using deleteLater() to prevent crashes The problem was that Qt tried to deliver an 'Enter' event to the dangling pointer that once pointed to the tool tip. Many thanks to G. Christ for finding a way to reproduce this crash!

I'm confident that all reports marked as duplicates are about the same issue because they all have the same pattern (crash in QCoreApplication::notifyInternal() after QApplicationPrivate::dispatchEnterLeave()). In the unlikely event that a crash with such a backtrace still happens in KDE 4.9.4 or later, please file a new report about it. Thanks to everyone who reported this issue!
