Description Johannes Schwall 2009-11-24 22:06:25 UTC 
Application that crashed: amarok
Version of the application: 2.2.0
KDE Version: 4.3.2 (KDE 4.3.2)
Qt Version: 4.5.2
Operating System: Linux 2.6.31-15-generic x86_64
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
I just clicked in the progress bar (not sure if it's called that way - I'm talking about the bar showing the progress of time while playing a song), very near the end of it, to skip a part of a song. Amarok then immediately crashed.

 -- Backtrace:

Sorry, but your backtrace is not useful, as you are lacking debugging symbols. If you can reproduce this bug, please check here on how to get a valid backtrace:

http://techbase.kde.org/Development/Tutorials/Debugging/How_to_create_useful_crash_reports

Since you are using Kubuntu, you will need amarok-dbg and phonon-dbg at least, ideally you should also have kdelibs5-dbg, libqt4-dbg and  libglib2.0-0-dbg. That should cover most of the crashes.

FWIW, this is apparently a crash in Phonon, not in Amarok, reassigning.

Thanks for the info. The crash report looked better than the "empty" ones produced without dbg packages, so I didn't understand why this one should be useless (as I was told by the bug reporting tool, I must admit). I now added the missing ones (libglib2.0-0-dbg and phonon-dbg) and I'll try to reproduce the bug.
Comment 3 Johannes Schwall 2009-11-25 00:13:35 UTC 
(In reply to comment #1)

I was able to reproduce the bug, but unfortunately, the bug reporting tool still says that it's probably unusable. (Pasted below.)

Application: Amarok (amarok), signal: Floating point exception

Comment 4 Myriam Schweingruber 2009-12-11 23:58:15 UTC 
This is due to this line:
#5  0x00007fce3dfe5a03 in ?? () from
/usr/lib/xine/plugins/1.26/xineplug_dmx_ogg.so

So it still can't localize the origin of the bug properly. I fear it might be a problem with libxine itself. Strangely I can't reproduce this here with Amarok 2.2-git on Kubuntu 9.10 with KDE 4.3.4. No idea what goes wrong there.
Comment 5 Johannes Schwall 2010-03-09 22:39:13 UTC 
I just stumbled upon this bug report. I cannot add anything new and it didn't appear anymore. (Meanwhile I'm using KDE 4.4.1 and 2.2.2.) So I think this bug should be closed ...
Comment 6 Myriam Schweingruber 2010-08-14 11:29:32 UTC 
Thank you for the feedback. Closing. Feel free to reopen if you can reproduce this with KDE 4.5 or later.
