Description Ctibor Brančík 2010-12-30 14:30:08 UTC 
Application: amarok (2.3.2)
KDE Platform Version: 4.5.90 (4.6 RC1)
Qt Version: 4.7.1
Operating System: Linux 2.6.36-zen1 x86_64
Distribution (Platform): Gentoo Packages

-- Information about the crash:
- What I was doing when the application crashed: I loaded a random playlist of the songs from my collection (songs are stored localy and on nfsv4 share too [but access is not through kio-slaves it is mounted by system init scripts]) and minimized amarok to the tray. After some songs played, it crashed. I tried several times, it crashes randomly I haven't found any pattern in the crash.

The crash can be reproduced some of the time.

-- Backtrace:
Application: Amarok (amarok), signal: Illegal instruction
The current source language is "auto; currently asm".

Comment 1 Myriam Schweingruber 2011-01-04 03:55:02 UTC 
Could you please test with Amarok 2.4 beta?
Comment 2 Ctibor Brančík 2011-01-04 13:22:27 UTC 
Tha same happens, but output from the debug assistant is only: Application: Amarok (amarok), signal: Illegal instruction
Comment 3 Myriam Schweingruber 2011-01-05 01:55:33 UTC 
Thank you for the feedback.
Comment 4 Ctibor Brančík 2011-01-05 13:47:19 UTC 
I made mistake. Backtrace is here:

Comment 5 Myriam Schweingruber 2011-01-05 14:37:20 UTC 
The backtrace is the same, thank you for the feedback.
Comment 6 Ctibor Brančík 2011-02-03 15:54:46 UTC 
I have investigated thist matter further with 2.4 final release. This time with random playlist disabled. But it still crashes for me, however I probably discovered the cause - I have removed all the applets and it seems to be ok. But if I shall add the applet that fetches covers of the albums, it crashes immediately. I have another backtrace:

Is it the same or should I file separate bug for this.
Comment 7 Myriam Schweingruber 2011-03-19 11:50:56 UTC 
No, this is not the same crash, this time it is a duplicate of bug 253256, already solved in the upcoming 2.4.1. Please test with the current git version.

Yayesh: your crash is a totally different one and a duplicate of bug 263256.

Ctibor: can you reproduce the original crash again or does it always produce the same backtrace as the one in comment #6?

Comment 11 Ctibor Brančík 2011-04-19 15:38:09 UTC 
Oh, it seems like Yayesh's backtrace. I am not sure if I can reproduce original problem because I had to change amarok configuration due to the crash and I can't really remember original settings. It is also possible that problem with cover manager does not allow me to test it.
Comment 12 Myriam Schweingruber 2011-04-20 11:08:52 UTC 
Well, it is just likely the original bug was fixed already, and what now appears is another one. Marking as duplicate.
