Description Vivek 2010-10-25 03:25:47 UTC

Version:           2.3.2 (using KDE 4.5.2) 
OS:                Linux

Amarok frequently crashes on my computer, openSUSE 11.3 with KDE 4.5.2. When playing through a playlist, it crashes when starting the next song.  At certain times, I've thought it was related to a particular album or song, while at other times I can't reproduce it at all.  Some days it's worse than others, crashing on literally every other song, while on other days it will play for an hour without crashing.   

The auto-generated backtraces are ranked by the Dr.Konqi bug wizard as 1 star/not very useful.  So I followed the debugging steps and ran it under gdb, with the --nofork --debug options.

One factor I've found a bit bizarre is that Amarok is about ten times less likely to crash with gdb.  (Could this be a packaging problem?) 

There are still some ?? symbols in this backtrace (related to "libavcodec" and some others), so I'm not sure it will be enough to solve the problem.  Still, I hope someone will be able to instruct me on how to further debug this problem.  


Backtrace from gdb:

Reproducible: Sometimes

Steps to Reproduce:
Start Amarok,
Populate a playlist with mp3, wma, ogg files,
Amarok will crash sooner or later, sometimes within 2 songs, almost always within the hour.  The crash happens regardless of whether the computer is unattended or being actively used.

Note: running amarok under gdb > run -nofork --debug makes amarok crash much more rarely.

Actual Results:  
Crash at the end of a song/beginning of another song.

Expected Results:  
Not crash.

OS: Linux (i686) release 2.6.34.7-0.4-default
Compiler: gcc

There might indeed be a packaging problem in OpenSuSE, as bug 253055 suggests as well. Unfortunately the gdb backtrace is not exactly very good, could you please try to reproduce it again, running it as follow:

gdb amarok
run -d --nofork

once the crash happens type

bt

and give the output.

Thank you for the feedback. The crash lies in the codecs, please check with your distribution.
