WindowServer crashes after key stroke

From time to time, WindowServer crashes spontaneously after a keystroke.
Steps to Reproduce:
This issue cannot be deterministically reproduced. Press a key (if I'm not mistaken, it has always happened in a Carbon/PPC application - Eudora)
The keystroke is processed normally
WindowServer crashes, taking all user processes with it
It has happened three times for me (twice in November, once today), totally randomly. I can't associate any specific circumstances with it except that I believe I always had Eudora frontmost, but that could also be because that's what I use most. The fact that the problem didn't happen before November doesn't mean anything - I only upgraded from a Powerbook with Tiger to a MBP with Leopard in November.
Stack trace of the crashing thread has always been identical, so I only provide one. See attachment.
