Version: 1.11.2 (using KDE 4.2.2) OS: Linux Installed from: Ubuntu Packages Quite often, while trying to delete an unread message from an IMAP folder, the application crashes. The backtrace I get is the following one: (lots of "(no debugging symbols found)") 0xb7f59430 in __kernel_vsyscall () [Current thread is 0 (process 16314)] Thread 1 (Thread 0xb3bc4b40 (LWP 16314)): #0 0xb7f59430 in __kernel_vsyscall () #1 0xb5b5b7a6 in nanosleep () from /lib/tls/i686/cmov/libc.so.6 #2 0xb5b5b5be in sleep () from /lib/tls/i686/cmov/libc.so.6 #3 0xb7e028b2 in ??

If you can reproduce the crash at will, may you read http://techbase.kde.org/Development/Tutorials/Debugging/How_to_create_useful_crash_reports and post a complete backtrace here? You need to install the "kdepim-dbg" package. Thanks
Changing the bug status until we get a backtrace (see comment #2)
I have been able to reproduce it one more time. Tha crash was produced while trying to delete a message that had not yet been displayed in the message content view. Here is the backtrace: Aplicación: KMail (kmail), señal SIGSEGV Thread 1 (Thread 0xb3d21b40 (LWP 4249)): [KCrash Handler] #6 KMail::FolderJob::msgList (this=0x350031) at /usr/include/qt4/QtCore/qlist.h:111 #7 0xb7557d9b in KMAcctImap::ignoreJobsForMessage (this=0x87538c8, msg=0x9505218) at /build/buildd/kdepim-4.2.2/kmail/kmacctimap.cpp:215 #8 0xb75709e5 in KMFolderImap::ignoreJobsForMessage (this=0x8777288, msg=0x9505218) at /build/buildd/kdepim-4.2.2/kmail/kmfolderimap.cpp:1562 #9 0xb7693cc6 in KMMoveCommand::execute (this=0x93ab260) at /build/buildd/kdepim-4.2.2/kmail/kmcommands.cpp:2086 #10 0xb7677322 in KMCommand::slotPostTransfer (this=0x93ab260, result=KMCommand::OK) at /build/buildd/kdepim-4.2.2/kmail/kmcommands.cpp:276 #11 0xb7682d74 in KMCommand::qt_metacall (this=0x93ab260, _c=QMetaObject::InvokeMetaMethod, _id=5, _a=0xbfed3e5c) at /build/buildd/kdepim-4.2.2/obj-i486-linux-gnu/kmail/kmcommands.moc:87 #12 0xb7695cba in KMMoveCommand::qt_metacall (this=0x93ab260, _c=QMetaObject::InvokeMetaMethod, _id=9, _a=0xbfed3e5c) at /build/buildd/kdepim-4.2.2/obj-i486-linux-gnu/kmail/kmcommands.moc:1706 #13 0xb7695d82 in KMDeleteMsgCommand::qt_metacall (this=0x93ab260, _c=QMetaObject::InvokeMetaMethod, _id=9, _a=0xbfed3e5c) at /build/buildd/kdepim-4.2.2/obj-i486-linux-gnu/kmail/kmcommands.moc:1758 #14 0xb6001ca8 in QMetaObject::activate (sender=0x93ab260, from_signal_index=4, to_signal_index=4, argv=0xbfed3e5c) at kernel/qobject.cpp:3069 #15 0xb6002932 in QMetaObject::activate (sender=0x93ab260, m=0xb7afd9b4, local_signal_index=0, argv=0xbfed3e5c) at kernel/qobject.cpp:3143 #16 0xb7673993 in KMCommand::messagesTransfered (this=0x93ab260, _t1=KMCommand::OK) at /build/buildd/kdepim-4.2.2/obj-i486-linux-gnu/kmail/kmcommands.moc:102 #17 0xb769202c in KMCommand::transferSelectedMsgs (this=0x93ab260) at /build/buildd/kdepim-4.2.2/kmail/kmcommands.cpp:370 #18 0xb769228f in KMCommand::slotStart (this=0x93ab260) at /build/buildd/kdepim-4.2.2/kmail/kmcommands.cpp:268 #19 0xb7682d83 in KMCommand::qt_metacall (this=0x93ab260, _c=QMetaObject::InvokeMetaMethod, _id=4, _a=0xbfed4058) at /build/buildd/kdepim-4.2.2/obj-i486-linux-gnu/kmail/kmcommands.moc:86 #20 0xb7695cba in KMMoveCommand::qt_metacall (this=0x93ab260, _c=QMetaObject::InvokeMetaMethod, _id=8, _a=0xbfed4058) at /build/buildd/kdepim-4.2.2/obj-i486-linux-gnu/kmail/kmcommands.moc:1706 #21 0xb7695d82 in KMDeleteMsgCommand::qt_metacall (this=0x93ab260, _c=QMetaObject::InvokeMetaMethod, _id=8, _a=0xbfed4058) at /build/buildd/kdepim-4.2.2/obj-i486-linux-gnu/kmail/kmcommands.moc:1758 #22 0xb6001ca8 in QMetaObject::activate (sender=0x9ca3250, from_signal_index=4, to_signal_index=4, argv=0x0) at kernel/qobject.cpp:3069 #23 0xb6002932 in QMetaObject::activate (sender=0x9ca3250, m=0xb60dd908, local_signal_index=0, argv=0x0) at kernel/qobject.cpp:3143 #24 0xb60070a7 in QSingleShotTimer::timeout (this=0x9ca3250) at .moc/release-shared/qtimer.moc:76 #25 0xb60071cc in QSingleShotTimer::timerEvent (this=0x9ca3250) at kernel/qtimer.cpp:298 #26 0xb5ffc15f in QObject::event (this=0x9ca3250, e=0xbfed44dc) at kernel/qobject.cpp:1082 #27 0xb6298e9c in QApplicationPrivate::notify_helper (this=0x85b5660, receiver=0x9ca3250, e=0xbfed44dc) at kernel/qapplication.cpp:4084 #28 0xb62a119e in QApplication::notify (this=0xbfed47f8, receiver=0x9ca3250, e=0xbfed44dc) at kernel/qapplication.cpp:3631 #29 0xb7eef94d in KApplication::notify (this=0xbfed47f8, receiver=0x9ca3250, event=0xbfed44dc) at /build/buildd/kde4libs-4.2.2/kdeui/kernel/kapplication.cpp:307 #30 0xb5feba3b in QCoreApplication::notifyInternal (this=0xbfed47f8, receiver=0x9ca3250, event=0xbfed44dc) at kernel/qcoreapplication.cpp:602 #31 0xb601ad71 in QTimerInfoList::activateTimers (this=0x85b7e44) at ../../include/QtCore/../../src/corelib/kernel/qcoreapplication.h:213 #32 0xb60174e0 in timerSourceDispatch (source=0x85b7e10) at kernel/qeventdispatcher_glib.cpp:164 #33 0xb4423b88 in g_main_context_dispatch () from /usr/lib/libglib-2.0.so.0 #34 0xb44270eb in ??
