Thanks Slavek.
I had no problem with Amarok until Friday night/Saturday morning, then from Saturday night it started crashing. In between I had rebuilt a base system (everything up to tdebase). Yesterday I extended the rebuild process and also included Amarok, but even after that it still crashes.
How recent are your preliminary-stable-builds?
