I cannot reproduce the problem with xmms-1.2.7. Is your kwin recent? Could you rebuild kwin with debug info enabled, and provide a better backtrace? ( After kwin crashes and you see drkonqi, switch to text console, log in, do 'ps ux| grep kwin', start gdb, and in gdb do 'attach <pid of kwin>'; then type 'up' until you reach the level above "#5 <signal handler called>" and there type 'list'.)
ok, new backtrace follows. attaching gdb was not successful, because there was no symbol table loaded (gdb says: "use file command instead"). please give me a hint how to proceed then. kwin is recent when i'm using cvs, isn't it? xmms is xmms-1.2.7-r11 (could update to r20, but that shouldn't matter).

The line numbers from the backtrace were enough for me to find the problem. It should be fixed now.
