first crash while hovering over last opened file menu of kwrite

When I hover the mouse pointer over the last opened file menu entry in KWin
X.org with Radeon KMS reliably crashes here. I tried three times - I get
slightly different backtraces, but Radeon DRI /usr/lib/dri/r300_dri.so is
always involved. I attach the logs in few moments.

I am using the following debian packages:
