Version:           1.2.0 (using KDE Devel)
Installed from:    Compiled sources
Compiler:          gcc-3.3 
OS:          Linux

My current "setup" is this: I compile parts of KDE in the background so that the system load is rather high (Dual PIII-550 and make -j 2).
Playing a list of ogg files in noatun works well unless I close an application window like the one from qt-assistant. Most time artsd crashes with the appended backtrace and the current ogg file is skipped to the end.

Thanks for having a look into this.
