Backtrace stopped: frame did not save the PC
Amarok starts up, but freezes after a few seconds. Its backtrace looks similar:

Sometimes, the whole desktop freezes: the applications keep running (e.g., the
System Monitor applet keeps repainting itself), but nothing responds to mouse
or keyboard events - not even the window manager.
I tried logging out and logging in a few times - no difference.
