comment #26 of bug #201111 (https://bugs.kde.org/show_bug.cgi?id=201111#c26) might also be related to this.
Comment 1 Dario Andres 2009-10-09 00:41:27 UTC 
The backtrace is also related/the same as bug 207211 (which is marked as fixed). - Is your Git build updated? 
Thanks
Comment 2 Andreas Stangl 2009-10-09 16:47:04 UTC 
Yes, I updated amarok right before I reported this bug.
Comment 3 Andreas Stangl 2009-10-09 20:31:19 UTC 
Updated again, but the crash is still there. Full stack trace -> http://pastebin.com/f6c6801f5 (I don't wanna paste an almost duplicated dump here again, url will not expire)
Comment 4 Ekeluo Chukwuogor 2009-10-16 05:57:49 UTC 
I have this bug, using 2.2 latest on kubuntu karmic. Amarok crashes whenever I decide to change the rating I just gave a song.
