Description José Alejandro Carrillo Neira 2010-03-03 13:19:09 UTC 
Application that crashed: amarok
Version of the application: 2.2.2
KDE Version: 4.3.4 (KDE 4.3.4)
Qt Version: 4.5.3
Operating System: Linux 2.6.32-trunk-amd64 x86_64
Distribution: Debian GNU/Linux testing (squeeze)

What I was doing when the application crashed:
After I added the library folder, amarok crashed without a message, other than the Crash Handler.

This has already happened with another music player, minirok, and I believe this might as well be related to GStreamer, because rhythmbox refuses to play m4a files, blaming a failure to negotiate with GStreamer.

My music library is mainly composed of m4a files, lossless, and a lot of them are named with Japanese characters. I don't think it could be related, but I'm adding it anyway, just in case.

 -- Backtrace:
Application: Amarok (amarok), signal: Segmentation fault

commit ccbc1343545cb93acb4e3cfb02fc4bc2a4af4960
Author: Mark Kretschmann <kretschmann@kde.org>
Date:   Sun Mar 14 12:47:42 2010 +0100

    Try to fix an obscure crash in the config dialog code.
    
    I'm not really sure how this crash could happen in the first place,
    and neither can I reproduce it. However, the problem seems to be a
    dangling pointer, so our SmartPointerList should cure that.
    
    BUG: 229243

Sorry, but it is not fixed, I had the exact same crash with a fresh install in current git build a few minutes ago. Current head is at 352cb0e:

    This reverts commit ccbc1343545cb93acb4e3cfb02fc4bc2a4af4960.
    
    Turns out that this patch was pointless and didn't fix anything.

This bug is possibly related to Bug 231398
Comment 5 Mark Kretschmann 2010-06-01 18:20:14 UTC 
This issue was apparently a KDE bug, should be fixed with the latest KDE version :)

Which version is that?
It happens with KDE 4.4.5
Comment 8 Myriam Schweingruber 2010-09-09 18:51:29 UTC 
Reopening, as it is not clear when and by what this was fixed.
Comment 9 Myriam Schweingruber 2010-09-09 18:52:11 UTC 
Last report was with Amarok 2.3.1 and KDE 4.4.5

Closing for lack of feedback. This is likely already solved in Amarok 2.4. Feel free to reopen this report if you can reproduce this with Amarok 2.4 or later.
