Bug 215943

Application that crashed: amarok
Version of the application: 2.2.0
KDE Version: 4.3.2 (KDE 4.3.2)
Qt Version: 4.5.2
Operating System: Linux 2.6.31-14-generic x86_64
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
While playing in a dynamic playlist I rated the currently played song with 3 stars and immediately changed it to 3.5. Amarok just crashed. This has happened quite often but it cannot be reproduced everytime.

(As the bug reporting assistant does not let me search for bugs by number, I don't know how to find bug #200546, which should be the one this is similar to. I only found one similar which was marked as a duplicate of #200546.)
