IIUC, the only connection between them is via the X server. You could
maybe connect an strace process to the X server to see what its sending to
the WM, but it will be hard to spot whats causing the problem I think.

I guess youve allready tried getting a core dump from the WM?

I wonder what jamin could be doing that so unusual?
