Description Eike Trumann 2013-06-23 09:16:54 UTC

Application: amarok (2.7.0)
KDE Platform Version: 4.10.3
Qt Version: 4.8.4
Operating System: Linux 3.8.0-12-generic x86_64
Distribution: Ubuntu 13.04

-- Information about the crash:
- What I was doing when the application crashed:
Direkt nach dem Systemstart auf einem Kubuntu 13/04 hat Amarok einen Segfault verursacht. Ich nehme an, das das kein gewünschtes Verhalten ist. Die Musikbibliothek liegt im Wesentlichen auf einem NTFS-Laufwerk, dass zu diesem Zeitpunkt noch nicht eingehängt wurde.

-- Backtrace:
Application: Amarok (amarok), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".

Comment 1 Myriam Schweingruber 2013-06-23 10:32:42 UTC

English, please.

Is this crash reproducible? I also strongly suggest you upgrade to Amarok 2.7.1, it is available in the Kubuntu backports PPA

Comment 2 Eike Trumann 2013-06-23 10:50:18 UTC

In English:
I have Amarok configured for autostart on my Kubuntu 13/04 system (amd64). After last reboot i the problem reporting tool popped up stating Amarok segfaulted. I don't have any idea why this happend as staring Amarok afterwards was no problem. The problem did not reoccur after the next reboot. I just felt this should reported as I don't like segfaults. The only thing thats anyhow special about my configuration is that my music library is stores on an NTFS partition which is not mounted on system startup, but only if needed by using Dolphin.

Comment 3 Myriam Schweingruber 2013-06-23 15:30:11 UTC

I fear there is not much we can do about that, a crash needs to be reproducible to be fixed.

FWIW: if you set Amarok to autostart you should also make sure the collection is available when Amarok starts, else this is a potential for other crashes.

Comment 4 Eike Trumann 2013-06-23 21:06:03 UTC

It's totally OK, for me everxthing works well. I just provided the bug report because the reporting tool told me so. 
P. S.: I realy like Amarok. Thanks for the good software.
