Just tabbed; I can't reproduce it using the tiled layout.  To answer
Don's question, yes, just fire up glxgears - you can almost see the
gears before everything crashes.  Works every time.  I haven't seen
anything similar happen with any other programs, but I don't run much
besides iceweasel, urxvt, and emacs.

I have reproduced this both on an amd64 with Xinerama and on an i386
without.  In both cases I'm running Debian testing with ghc-6.6.1.  For
some reason the i386 doesn't show a message in ~/.xsession-errors like
the one above from the amd64.
