Just came across this; it is present in (at least) 23.2, and in trunk.
I haven't had time to debug further; any help welcome.  The backtrace is
from trunk.

emacs -Q

I have backported the trunk fix to the emacs-23 brach (there seems to be
no safer complete solutions).  Closing Bug#8219 and Bug#1242.
