Binary package hint: amarok

After upgrading from 8.10 to 9.04, amarok crashes very often (more than once/hour) while I am just playing back music from a randomly populated dynamic list.
Qt: 4.5.0
KDE: 4.2.2 (KDE 4.2.2)
Amarok: 2.0.2 (Installed: 2:2.0.2mysql5.1.30-0ubuntu3)
Linux 2.6.28-11-generic #42-Ubuntu SMP Fri Apr 17 01:58:03 UTC 2009 x86_64 GNU/Linux
