Can you find steps to reproduce the crash?
On Monday 12 February 2007 12:33:31 pm Philip Rodrigues wrote: [bugs.kde.org quoted mail] I'll report my attempts to reproduce the bug. It occurred after reading and saving an unknown number of articles. Bob
Step to reproduce: - Open kontact - Open knode within kontact - Open an article in an external window - Close kontact (this let the previous external windows open) - Save the article (from the external window) => crash Application: Kontact (kontact), signal: Segmentation fault [KCrash Handler] #5 0x00007fa2e9a63c83 in QListData::isEmpty (this=0x3860ac8) at /usr/include/qt4/QtCore/qlist.h:88 #6 0x00007fa2e9a78c13 in QList<KMime::Content*>::isEmpty (this=0x3860ac8) at /usr/include/qt4/QtCore/qlist.h:123 #7 0x00007fa2e9a76dec in KMime::Content::encodedContent (this=0x3860a00, useCrLf=false) at /home/kde/dev/src/kdepimlibs/kmime/kmime_content.cpp:387 #8 0x00007fa2d6709e5e in KNArticleManager::saveArticleToFile (this=0x349a610, a=0x3860a00, parent=0x3865e30) at /home/kde/dev/src/kdepim/knode/knarticlemanager.cpp:110 #9 0x00007fa2d6754aad in KNode::ArticleWidget::slotSave (this=0x3865e30) at /home/kde/dev/src/kdepim/knode/articlewidget.cpp:1257 #10 0x00007fa2d675aa7f in KNode::ArticleWidget::qt_metacall (this=0x3865e30, _c=QMetaObject::InvokeMetaMethod, _id=8, _a=0x7ffffbf834d0) at /home/kde/dev/build/kdepim/knode/articlewidget.moc:130 #11 0x00007fa2ef1dc862 in QMetaObject::activate (sender=0x393f710, from_signal_index=<value optimized out>, to_signal_index=6, argv=0x3df0160) at kernel/qobject.cpp:3120 #12 0x00007fa2ede774e7 in QAction::triggered (this=0x3860ac8, _t1=false) at .moc/release-shared/moc_qaction.cpp:236 #13 0x00007fa2ede78960 in QAction::activate (this=0x393f710, event=<value optimized out>) at kernel/qaction.cpp:1160 #14 0x00007fa2ede7b477 in QAction::event (this=0x3860ac8, e=<value optimized out>) at kernel/qaction.cpp:1079 #15 0x00007fa2eff78927 in KAction::event (this=0x393f710, event=0x7ffffbf83a50) at /home/kde/dev/src/kdelibs/kdeui/actions/kaction.cpp:88 #16 0x00007fa2ede7d4fd in QApplicationPrivate::notify_helper (this=0x2338c40, receiver=0x393f710, e=0x7ffffbf83a50) at kernel/qapplication.cpp:4057 #17 0x00007fa2ede8577a in QApplication::notify (this=0x7ffffbf86150, receiver=0x393f710, e=0x7ffffbf83a50) at kernel/qapplication.cpp:4022 #18 0x00007fa2f004873f in KApplication::notify (this=0x7ffffbf86150, receiver=0x393f710, event=0x7ffffbf83a50) at /home/kde/dev/src/kdelibs/kdeui/kernel/kapplication.cpp:307 #19 0x00007fa2ef1c6e4c in QCoreApplication::notifyInternal (this=0x7ffffbf86150, receiver=0x393f710, event=0x7ffffbf83a50) at kernel/qcoreapplication.cpp:610 #20 0x00007fa2edeb2e6d in QShortcutMap::dispatchEvent (this=<value optimized out>, e=0x7ffffbf83f80) at ../../include/QtCore/../../src/corelib/kernel/qcoreapplication.h:213 #21 0x00007fa2edeb4ccc in QShortcutMap::tryShortcutEvent (this=0x2338d58, o=<value optimized out>, e=0x7ffffbf83f80) at kernel/qshortcutmap.cpp:369 #22 0x00007fa2ede867a1 in QApplication::notify (this=0x7ffffbf86150, receiver=0x3880110, e=0x7ffffbf83f80) at kernel/qapplication.cpp:3646 #23 0x00007fa2f004873f in KApplication::notify (this=0x7ffffbf86150, receiver=0x3880110, event=0x7ffffbf83f80) at /home/kde/dev/src/kdelibs/kdeui/kernel/kapplication.cpp:307 #24 0x00007fa2ef1c6e4c in QCoreApplication::notifyInternal (this=0x7ffffbf86150, receiver=0x3880110, event=0x7ffffbf83f80) at kernel/qcoreapplication.cpp:610 #25 0x00007fa2edf12774 in QKeyMapper::sendKeyEvent (keyWidget=0x3880110, grab=<value optimized out>, type=QEvent::KeyPress, code=83, modifiers={i = -67615568}, text=@0x7ffffbf844a0, autorepeat=false, count=1, nativeScanCode=39, nativeVirtualKey=115, nativeModifiers=20) at kernel/qkeymapper_x11.cpp:1675 #26 0x00007fa2edf14aa9 in QKeyMapperPrivate::translateKeyEvent (this=0x237a560, keyWidget=0x3880110, event=0x7ffffbf85d80, grab=false) at kernel/qkeymapper_x11.cpp:1645 #27 0x00007fa2edeed626 in QApplication::x11ProcessEvent (this=0x7ffffbf86150, event=0x7ffffbf85d80) at kernel/qapplication_x11.cpp:3459 #28 0x00007fa2edf164d4 in x11EventSourceDispatch (s=0x233c380, callback=0, user_data=0x0) at kernel/qguieventdispatcher_glib.cpp:146 #29 0x00007fa2e8538e4a in g_main_context_dispatch () from /usr/lib/libglib-2.0.so.0 #30 0x00007fa2e853c510 in ??
