Comment 1 Myriam Schweingruber 2013-10-27 10:44:11 UTC
Please install the debugging symbols for the phonon-backend-vlc and provide a new backtrace, this might not be an Amarok problem.
Comment 2 Jonathan Kaye 2013-10-27 11:05:25 UTC
Sorry Ignore the comments about knotify. That is another problem which may or may not be related to the amarok crashes.

The 2nd backtrace took place after I installed phonon-backend-vlc-dbg.
jdk
Comment 5 Myriam Schweingruber 2013-10-27 18:01:12 UTC
Could you please try the phonon-backend-gstreamer instead? Looks like this is related to libvlc

This seems to be in fact a Debian specific bug, please report this downstream.

*** This bug has been marked as a duplicate of bug 326749 ***
Comment 7 Jonathan Kaye 2013-10-27 18:41:01 UTC
Yes, I tried that and it fixed the problem. Do you need any more information? Thanks so much for your help.
Comment 8 Myriam Schweingruber 2013-10-27 19:57:07 UTC
No, thank you, clearly a problem with the libvlc library in Debian. Now the ball is in their camp.
