FWIW, I strongly suggest you use either the phonon gstreamer or vlc backend. the xine backend is deprecated and unmaintained. Which applets are active in the Context View? Is this crash reproducible? Then please provide steps how to reproduce it. Created attachment 64022 [details]
New crash information added by DrKonqi
amarok (2.4-GIT) on KDE Platform 4.7.1 (4.7.1) using Qt 4.7.4
Just had the same crash here, starting a mp3 file, using the gstreamer backend 4.5.1, on Kubuntu 11.10 beta2, Amarok current git.

The crash is sadly not reproducible, so far I only had that once. A possible workaround is to disable animations in the Context View. I just ran into this bug after pulling the latest amarok from git and doing a dist upgrade. Qt was 4.7.3 i think, now it's 4.7.4. My distribution is opensuse 11.4. I can reproduce this crash every time, disabling the collapse animation avoids it.

Changing priority. OK, switched to the VLC backend (version 0.3.2) and disabled the context applet collapse animations and now the crashes no longer occur (yay!). Am using amarok from git and KDE 4.6.2. My distribution is Ubuntu 11.04. *** Bug 283220 has been marked as a duplicate of this bug. *** Created attachment 64531 [details]

amarok (2.4-GIT) on KDE Platform 4.7.2 (4.7.2) using Qt 4.7.4
I've the same problem here. I'm using gstreamer.
Amarok crash when we start playng a song.
Normally this problem appear if we play a flac file.

I'm getting the same crash using the gstreamer backend here. No pulseaudio; just regular old ALSA, thanks. I noticed it seems to happen around the time it switches songs, leading me to believe it may be related to the OSD (a race condition or something). I'd test further, but I'm supposed to be doing work right now. ;)
