Version: 4.00.72 (using Devel) Installed from: Compiled sources OS: Linux I used ALT+F2 to launch a program (doesn't matter). The program lanches ok. After a while (several minutes), a crash handler appears for "Run Command Interface".

close... i need the same crash, but with a backtrace going through the startup notification code .. damn multithreading and race conditions.
I also go the same in 4.0.82 except the bug report came up immediatly after launching the application, here is the trace: Application: Run Command Interface (krunner), signal SIGSEGV [Thread debugging using libthread_db enabled] [New Thread 0xb534b940 (LWP 30743)] [New Thread 0xaf850b90 (LWP 30823)] [New Thread 0xb0051b90 (LWP 30822)] [New Thread 0xb0852b90 (LWP 30821)] [New Thread 0xb1053b90 (LWP 30820)] [New Thread 0xb1854b90 (LWP 30819)] [New Thread 0xb2055b90 (LWP 30818)] [New Thread 0xb2856b90 (LWP 30817)] [New Thread 0xb3057b90 (LWP 30816)] [New Thread 0xb3858b90 (LWP 30815)] [KCrash handler] #6 0xb64dd5ff in QIODevice::seek () from /usr/lib/libQtCore.so.4 #7 0xb64c4a00 in QBuffer::seek () from /usr/lib/libQtCore.so.4 #8 0xb6fe99b2 in KSycocaDict::Private::offsetForKey (this=0x80e1008, key=@0xbfcc685c) at /opt/kde4/kde/src/KDE/kdelibs/kdecore/sycoca/ksycocadict.cpp:518 #9 0xb6fea8db in KSycocaDict::find_string (this=0x80e41b0, key=@0xbfcc685c) at /opt/kde4/kde/src/KDE/kdelibs/kdecore/sycoca/ksycocadict.cpp:142 #10 0xb6f6831d in KServiceFactory::findServiceByDesktopName (this=0x82c4120, _name=@0xbfcc685c) at /opt/kde4/kde/src/KDE/kdelibs/kdecore/services/kservicefactory.cpp:115 #11 0xb6f60b6d in KService::serviceByDesktopName (_name=@0xbfcc68b4) at /opt/kde4/kde/src/KDE/kdelibs/kdecore/services/kservice.cpp:581 #12 0xb716f219 in KRun::runCommand (cmd=@0xbfcc6924, execName=@0xbfcc68fc, iconName=@0xbfcc68fc, window=0x0, asn=@0xbfcc68f8) at /opt/kde4/kde/src/KDE/kdelibs/kio/kio/krun.cpp:800 #13 0xb716f2ea in KRun::runCommand (cmd=@0xbfcc6924, window=0x0) at /opt/kde4/kde/src/KDE/kdelibs/kio/kio/krun.cpp:791 #14 0xb3ab8115 in ShellRunner::run (this=0x822c118, context=@0x80a2260, match=@0x8247414) at /opt/kde4/kde/src/KDE/kdebase/workspace/plasma/runners/shell/shellrunner.cpp:101 #15 0xb7e0d775 in Plasma::QueryMatch::run (this=0x8247414, context=@0x80a2260) at /opt/kde4/kde/src/KDE/kdebase/workspace/libs/plasma/querymatch.cpp:207 #16 0xb7e1078b in Plasma::RunnerManager::run (this=0x8156b70, match=@0x8247414) at /opt/kde4/kde/src/KDE/kdebase/workspace/libs/plasma/runnermanager.cpp:379 #17 0xb7eea6d4 in ResultItem::run (this=0x8267f48, manager=0x8156b70) at /opt/kde4/kde/src/KDE/kdebase/workspace/krunner/resultitem.cpp:393 #18 0xb7eedd65 in ResultScene::run (this=0x816c8a0, item=0x8267f48) at /opt/kde4/kde/src/KDE/kdebase/workspace/krunner/resultscene.cpp:327 #19 0xb7ee28ee in Interface::run (this=0x80fb1b8, item=0x8267f48) at /opt/kde4/kde/src/KDE/kdebase/workspace/krunner/interface.cpp:403 #20 0xb7ee2935 in Interface::runDefaultResultItem (this=0x80fb1b8) at /opt/kde4/kde/src/KDE/kdebase/workspace/krunner/interface.cpp:410 #21 0xb7ee3235 in Interface::qt_metacall (this=0x80fb1b8, _c=QMetaObject::InvokeMetaMethod, _id=7, _a=0xbfcc6af8) at /opt/kde4/kde/build/KDE/kdebase/workspace/krunner/interface.moc:97 #22 0xb65564f9 in QMetaObject::activate () from /usr/lib/libQtCore.so.4 #23 0xb6556bc2 in QMetaObject::activate () from /usr/lib/libQtCore.so.4 #24 0xb6d4c43f in KComboBox::returnPressed (this=0x8146118) at /opt/kde4/kde/build/KDE/kdelibs/kdeui/kcombobox.moc:160 #25 0xb6d4d17b in KComboBox::qt_metacall (this=0x8146118, _c=QMetaObject::InvokeMetaMethod, _id=0, _a=0xbfcc6c28) at /opt/kde4/kde/build/KDE/kdelibs/kdeui/kcombobox.moc:104 #26 0xb6d626aa in KHistoryComboBox::qt_metacall (this=0x8146118, _c=QMetaObject::InvokeMetaMethod, _id=51, _a=0xbfcc6c28) at /opt/kde4/kde/build/KDE/kdelibs/kdeui/khistorycombobox.moc:76 #27 0xb65564f9 in QMetaObject::activate () from /usr/lib/libQtCore.so.4 #28 0xb6556bc2 in QMetaObject::activate () from /usr/lib/libQtCore.so.4 #29 0xb5edc0c7 in QLineEdit::returnPressed () from /usr/lib/libQtGui.so.4 #30 0xb5ee3600 in QLineEdit::keyPressEvent () from /usr/lib/libQtGui.so.4 #31 0xb6d6f001 in KLineEdit::keyPressEvent (this=0x816bfb8, e=0xbfcc7524) at /opt/kde4/kde/src/KDE/kdelibs/kdeui/widgets/klineedit.cpp:998 #32 0xb5b996f4 in QWidget::event () from /usr/lib/libQtGui.so.4 #33 0xb5ee410f in QLineEdit::event () from /usr/lib/libQtGui.so.4 #34 0xb6d6b62f in KLineEdit::event (this=0x816bfb8, ev=0xbfcc7524) at /opt/kde4/kde/src/KDE/kdelibs/kdeui/widgets/klineedit.cpp:1284 #35 0xb5e9f346 in QComboBox::keyPressEvent () from /usr/lib/libQtGui.so.4 #36 0xb6d61ce3 in KHistoryComboBox::keyPressEvent (this=0x8146118, e=0xbfcc7524) at /opt/kde4/kde/src/KDE/kdelibs/kdeui/widgets/khistorycombobox.cpp:345 #37 0xb5b996f4 in QWidget::event () from /usr/lib/libQtGui.so.4 #38 0xb5e9c067 in QComboBox::event () from /usr/lib/libQtGui.so.4 #39 0xb5b41c0c in QApplicationPrivate::notify_helper () from /usr/lib/libQtGui.so.4 #40 0xb5b46aec in QApplication::notify () from /usr/lib/libQtGui.so.4 #41 0xb6cb361f in KApplication::notify (this=0x805f698, receiver=0x8146118, event=0xbfcc7524) at /opt/kde4/kde/src/KDE/kdelibs/kdeui/kernel/kapplication.cpp:311 #42 0xb65416a9 in QCoreApplication::notifyInternal () from /usr/lib/libQtCore.so.4 #43 0xb5b9d22e in ??

Luke: that's a different crash, and is already fixed in trunk/
SVN commit 835987 by lunakl: Remove emitting of aboutToQuit() from KApplication::xioErrhandler() - the application is not about to quit, it is about to fall flat on its face. There is really not that much to do once KDE apps lose their connection to the X server. How that can happen while the X server still continues to run is a different question and I don't know the answer. It is quite possible it is caused by careless usage of one X connection from several threads concurrently without proper locking.

The last bt is unrelated (bug 177463), the second and third have been fixed, the first one is lacking debug infos and thus invalid. Lots of dbus-related issues have been fixed, since then, so I'm closing this one as well.
I confirm that latest KDE releases no longer crash. Si I choose de close this bug.
