My emacs had some Debian-provided patches, so I tried building fresh 
from CVS.  I'm still having the same problem, and I can still reliably 
reproduce the segfault.  Here's what I did:

$ cvs -d:pserver:anonymous@cvs.sv.gnu.org:/sources/emacs co emacs
$ cd emacs
$ ./configure
$ make bootstrap
$ make
$ ./src/emacs -Q

Then I evaluated the above snippet and hovered my mouse over something 
that produces a tooltip.  Presto, instant segfault.  If I leave out the 
':height 121' from the above snippet, no segfault.

Can anyone else reproduce this?

Thanks,
Richard
