Description Exoool 2012-09-12 04:55:15 UTC 
Application: amarok (2.5.0)
KDE Platform Version: 4.8.4 (4.8.4)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-30-generic-pae i686
Distribution: Ubuntu 12.04.1 LTS

-- Information about the crash:
- What I was doing when the application crashed:
Normal usage, the amarok is starting, but failed and show the bug report

- Custom settings of the application:
I guess it's because of the ampache configuration with Amarok.

-- Backtrace:
Application: Amarok (amarok), signal: Aborted
Using host libthread_db library "/lib/i386-linux-gnu/libthread_db.so.1".

Comment 1 Myriam Schweingruber 2012-09-12 08:26:21 UTC 
Looks like a problem with the network access handling, could you please upgrade your KDE and Amarok and try again? You will need the kubuntu backports PPA for this, see also http://kubuntu.org/news

Thanks for the guide.
I installed the PPA and now upgrading the system. Due to the slow internet here, it will take hours to finish. I will send an update here once it's done.
Comment 3 Exoool 2012-09-14 02:22:44 UTC 
I upgraded my Amarok and system(KDE) with kubuntu backports PPA enabled, but still Amarok crash every time before start succefully.  I also tried to purge Amarok and install it again but with no luck..
