Application: kmid (2.3.0) KDE Platform Version: 4.4.3 (KDE 4.4.3) Qt Version: 4.6.2 Operating System: Linux 2.6.32.12-115.fc12.x86_64 x86_64 Distribution: "Fedora release 12 (Constantine)" -- Information about the crash: First time after installing kmid on a new computer. I set "Settings->Configure Kmid->MIDI->Reset Mode" to "Yamaha XG" for my Yamaha db60xg (NEC XR-385) waveblaster card and clicked "Ok" and got the crash. It seems like once this crash happens, you can do the operation over again successfully without crashing. Therefore, this seems to be caused on the fist run/install of the program.... The following output on console from two different crashes. coggie-81-.../Music/MIDI> kmid kmid(19241)/kdeui (kdelibs): Attempt to use QAction "show_volume_pitch" with KXMLGUIFactory! kmid(19241)/kdeui (kdelibs): Attempt to use QAction "show_position" with KXMLGUIFactory! kmid(19241)/kdeui (kdelibs): Attempt to use QAction "show_codecs" with KXMLGUIFactory! kmid(19241)/kdeui (kdelibs): Attempt to use QAction "show_rhythm" with KXMLGUIFactory! kmid(19241)/kdecore (KConfigSkeleton) KCoreConfigSkeleton::writeConfig: kmid(19241)/kdecore (KConfigSkeleton) KCoreConfigSkeleton::writeConfig: kdeinit4: preparing to launch /usr/lib64/kde4/kio_trash.so kmid(19241)/kdecore (services) KMimeTypeFactory::parseMagic: Now parsing "/usr/share/mime/magic" kmid(19241)/kdecore (services) KMimeTypeFactory::parseMagic: Now parsing "/home/npm/.local/share/mime/magic" kmid(19241)/kdecore (KConfigSkeleton) KCoreConfigSkeleton::writeConfig: kDebugStream called after destruction (from void KDirWatchPrivate::removeEntry(KDirWatch*, KDirWatchPrivate::Entry*, KDirWatchPrivate::Entry*) file /builddir/build/BUILD/kdelibs-4.4.3/kio/kio/kdirwatch.cpp line 950) Cancelled INotify (fd 10, 1) for "/home/npm/.local/share//user-places.xbel" coggie-82-.../Music/MIDI> kdeinit4: preparing to launch /usr/bin/knotify4 Connecting to deprecated signal QDBusConnectionInterface::serviceOwnerChanged(QString,QString,QString) knotify(20226) KNotify::event: 1 ref= 0 [1] + Suspended (signal) kmid coggie-82-.../Music/MIDI> kdeinit4: preparing to launch /usr/lib64/libkdeinit4_kwalletd.so Connecting to deprecated signal QDBusConnectionInterface::serviceOwnerChanged(QString,QString,QString) Connecting to deprecated signal QDBusConnectionInterface::serviceOwnerChanged(QString,QString,QString) kdeinit4: preparing to launch /usr/lib64/kde4/kio_http.so kdeinit4: preparing to launch /usr/lib64/kde4/kio_http.so kded(18893)/kdecore (KLibrary) kde4Factory: The library "/usr/lib64/kde4/solid_networkmanager07.so" does not offer a qt_plugin_instance function. -- Backtrace: Application: KMid (kmid), signal: Segmentation fault 82 T_PSEUDO (SYSCALL_SYMBOL, SYSCALL_NAME, SYSCALL_NARGS) [Current thread is 1 (Thread 0x7f70b895b840 (LWP 18887))] Thread 2 (Thread 0x7f70acfba710 (LWP 18896)): #0 0x00000032a96d5193 in __poll (fds=<value optimized out>, nfds=<value optimized out>, timeout=<value optimized out>) at ../sysdeps/unix/sysv/linux/poll.c:87 #1 0x00007f70acfe1665 in drumstick::MidiClient::SequencerInputThread::run (this=0x1b8f9a0) at /usr/src/debug/drumstick-0.3.1/library/src/alsaclient.cpp:1734 #2 0x0000003be7c709a5 in QThreadPrivate::start (arg=0x1b8f9a0) at thread/qthread_unix.cpp:248 #3 0x00000032aa206a3a in start_thread (arg=0x7f70acfba710) at pthread_create.c:297 #4 0x00000032a96de62d in clone () at ../sysdeps/unix/sysv/linux/x86_64/clone.S:112 #5 0x0000000000000000 in ??

Confirmed. I'm working on this. I can reproduce this issue, with conditions: * There is no ~/.kde4/share/config/kmidrc configuration file. Removing this file the crash can be reproduced consistently. * There is only one MIDI output port available in the system. For instance, if drumstick-vpiano is started before kmid, the crash doesn't happen.
By the way, this does not depend on the "Reset mode" setting, or any other option in the Configuration dialog. For instance, changing the lyrics font size and pressing OK -> crash.
w/r/t/ the statement: "There is only one MIDI output port available in the system" ... this is not consistent with what I'm seeing, where I have many available MIDI ports, e.g.: on the machine that produced the crashdumps: port created: Midi-Through:midi/capture_1 port created: MT4:midi/playback_1 port created: MT4:midi/capture_1 port created: MT4:midi/playback_2 port created: MT4:midi/capture_2 port created: MT4:midi/playback_3 port created: MT4:midi/capture_3 port created: MT4:midi/capture_4 port created: MT4:midi/capture_5 port created: BCD3000:midi/playback_1 port created: BCD3000:midi/capture_1 port created: UM-2:midi/playback_1 port created: UM-2:midi/capture_1 port created: UM-2:midi/playback_2 port created: UM-2:midi/capture_2 port created: QMidiRoute:midi/capture_1 port created: QMidiRoute:midi/playback_2 port created: QMidiRoute:midi/playback_3 port created: QXGEdit:midi/playback_1 port created: QXGEdit:midi/capture_1 port created: QmidiNet:midi/playback_1 port created: QmidiNet:midi/capture_1 port created: QmidiNet:midi/playback_2 port created: QmidiNet:midi/capture_2 And on a different machine that has same behavior: port created: Midi-Through:midi/capture_1 port created: MT4:midi/playback_1 port created: MT4:midi/capture_1 port created: MT4:midi/playback_2 port created: MT4:midi/capture_2 port created: MT4:midi/playback_3 port created: MT4:midi/capture_3 port created: MT4:midi/capture_4 port created: MT4:midi/capture_5 port created: LPK25:midi/playback_1 port created: LPK25:midi/capture_1 port created: DJ-Console-(WE):midi/playback_1 port created: DJ-Console-(WE):midi/capture_1 port created: ICEnsemble-ICE1724:midi/playback_1 port created: ICEnsemble-ICE1724:midi/capture_1 port created: QmidiNet:midi/playback_1 port created: QmidiNet:midi/capture_1 port created: QmidiNet:midi/playback_2 port created: QmidiNet:midi/capture_2
I don't recognize your port list format. Maybe you are using jack-midi or something like that? I didn't test kmid using jack midi. Anyway, to reproduce the crash is not necessary to uninstall and reinstall kmid. It should be enough renaming or deleting the file named 'kmidrc' in ~/.kde4/share/config About the realtime settings. To perform the test without realtime priority enabled, you only need to edit your /etc/security/limits.conf file, leading the 'rtprio' line with a character '#' (comment), and restarting the session (logout/login).
SVN commit 1134129 by pedrol: ALSA backend. Removed a call to ALSAMIDIOutput::reloadDeviceList() from the MIDI event handling thread, because this method is not thread safe and it is not needed since 2.3.0 anyway. This fixes an ugly crash. BUG: 240394 M +1 -1 CMakeLists.txt M +2 -4 alsa/alsamidiobject.cpp M +0 -3 alsa/alsamidioutput.cpp WebSVN link: http://websvn.kde.org/?view=rev&revision=1134129
The list of midi devices is from qjackctl's output... they're all ALSA midi devices. They are not jack midi devices nor do I use Jack midi very much, and certainly not with kmid.
