- Populate playlist from file browser (right-click on directory name -> Load).  For the test, I used a small subtree -- 5 directories, 46 tracks total.
- Start playing.
- Re-populate the playlist with same contents (again by right-clicking and choosing "Load") several times; usually 3 or 4 times is enough to cause a crash.

I've rebuilt amarok with --enable-debug=full, run it under gdb and got this backtrace:
