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..
