Description Ben Gouhier 2010-05-16 10:18:21 UTC 
Application: amarok (2.3.0.90)
KDE Platform Version: 4.4.2 (KDE 4.4.2)
Qt Version: 4.6.2
Operating System: Linux 2.6.32-22-generic x86_64
Distribution: Ubuntu 10.04 LTS

-- Information about the crash:
Looking like a completely random crash. Already happened  several times for no reason.
I use Kubuntu 10.04 with amarok 2.3.1 beta, bespin as kwin decorations and theme and I recetly changed the swappiness value to 10 (instead of 60). I dont see what else could cause any instability.

The crash can be reproduced some of the time.

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

Reported using DrKonqi
Comment 1 Myriam Schweingruber 2010-08-09 14:00:25 UTC 
Can you reproduce this crash with Amarok 2.3.1 final, too?
Comment 2 Ben Gouhier 2010-08-10 08:19:19 UTC 
I haven't encountered this crashed yet in 2.3.1
Comment 3 Myriam Schweingruber 2010-08-10 09:18:04 UTC 
Thank ypou for the feedback. Closing for now, feel free to reopen this report if you can reproduce it with Amarok 2.3.1 or later.

New crash information added by DrKonqi

amarok (2.3.1.90) on KDE Platform 4.5.00 (KDE 4.5.0) using Qt 4.7.0

- What I was doing when the application crashed:

I see this bug is closed, but DrKonqi suggests they're related, so I'll append my report here, so that developers may evaluate whether it should be reopened.

I was listening to a track in the playlist, while I added an album to my watched folder. Hence, Amarok started scanning music, and, by the time I expected it to show the new album in my music collection, the sound started stuttering, and continued to do so for a couple of seconds after Amarok crashed and the window was nowhere to be seen.

Comment 5 Myriam Schweingruber 2010-08-21 02:13:59 UTC 
Reopening.
Comment 6 Myriam Schweingruber 2010-10-17 10:55:08 UTC 
Is this still valid for Amarok 2.3.2 or current git? I can't reproduce this here
Comment 7 Leonardo La Malfa 2010-10-17 11:17:19 UTC 
Myriam, I can't help with this one for I switched to Debian, which is frozen by now, so I'm currently using v. 2.3.1.
Comment 8 Myriam Schweingruber 2010-10-17 14:46:20 UTC 
LBut can you reproduce this with 2.3.1? The original reporter couldn't
Comment 9 Leonardo La Malfa 2010-10-17 15:50:07 UTC 
> LBut can you reproduce this with 2.3.1? The original reporter couldn't
No, I can't. The series of actions that triggered the crash I described in my report is something I do very often, but the crash didn't occur again ever since.
Comment 10 Myriam Schweingruber 2010-10-17 16:31:20 UTC 
Thank you for your fast feedback. I close this bug for now as fixed in 2.3.2 (since the last occasion this was reported was 2.3.1.90), feel free to reopen this if you can reproduce it with Amarok 2.3.2 or later.
