rhythmbox crashes on changing volume

Binary package hint: rhythmbox

Ubuntu 9.10.
rhythmbox 0.12.5-0ubuntu4 0

I tried to change volume using rhythmbox slider (on top right corner) or just using mouse wheel over this button.
But rhythmbox crashed.

I can reproduce it always if constantly change volume during 2-5 secons. Sometimes it crashes immediately.

gdb output:
