Version: 2.1.1 (using KDE 4.3.0) OS: Linux Installed from: Ubuntu Packages Application that crashed: amarok Version of the application: 2.1.1 KDE Version: 4.3.00 (KDE 4.3.0) Qt Version: 4.5.2 Operating System: Linux 2.6.30-10-generic i686 Distribution: Ubuntu 9.04 What I was doing when the application crashed: Steps to reproduce: 1. Start amaroK 2. Activate a dynamic playlist (e.g. play everything at random) 3. Start playing or remove objects from playlist (even, when not playing music) This is not always reproducible with the first try. Maybe you have to wait a while letting amarok playing music or do some more changes to the playlist. -- Backtrace: Application: Amarok (amarok), signal: Segmentation fault [Current thread is 0 (LWP 5290)] Thread 10 (Thread 0x283db90 (LWP 5310)): #0 0x001a8422 in __kernel_vsyscall () #1 0x4c7e5412 in pthread_cond_timedwait@@GLIBC_2.3.2 () from /lib/tls/i686/cmov/libpthread.so.0 #2 0x4e49eae3 in ??

I can't reproduce this at all with current Amarok 2.2-GIT. There has bee a lot of work on the dynamic playlists in the developer version, so consider this solved. FYI: Amarok is written without a capital K since over 3 years :)
