[Bug 852446] New: Phonon-backend-vlc crashed often
https://bugzilla.novell.com/show_bug.cgi?id=852446 https://bugzilla.novell.com/show_bug.cgi?id=852446#c0 Summary: Phonon-backend-vlc crashed often Classification: openSUSE Product: openSUSE 13.1 Version: Final Platform: x86-64 OS/Version: openSUSE 13.1 Status: NEW Severity: Normal Priority: P5 - None Component: Sound AssignedTo: tiwai@suse.com ReportedBy: wbauer@tmo.at QAContact: qa-bugs@suse.de Found By: --- Blocker: --- User-Agent: Mozilla/5.0 (X11; Linux) KHTML/4.11.3 (like Gecko) Konqueror/4.11 SUSE Since upgrading to 13.1 applications using Phonon (I'm using the VLC backend) often crash. This mostly happens when the system is under I/O load I think. I reported the problem at KDE and the Phonon maintainer suspects a multithreading issue in alsa. Please see the KDE bug here: https://bugs.kde.org/show_bug.cgi?id=328087 That bug report contains a backtrace as well, but I can of course attach a new one here as well if wanted. I also want to add that I didn't have any crashes on 12.3 with exact the same versions of KDE, Phonon, and VLC.

Still it's interesting why it appears on 13.1 while not on 12.3. There is no code change at all in this regard. Maybe just a coincidence...
Maybe a change in the kernel exposes this? As I said, I have the feeling it happens more often when the system is under I/O load, so maybe it's filesystem related? (I'm using reiserfs if it matters)
The fixed package is being built on OBS home:tiwai:branches:openSUSE:13.1:Update/alsa repo. It's not published, so grab the package via osc manually if you'd like to test.
Ok, I have installed those packages now. Will report back in a day or two. The crashes were quite easy to reproduce. They almost certainly happened when I was using Kontact and got notifications of new EMails... ;-) Should I provide the warning messages then? Where do they go to? (I guess /var/log/messages?) -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
