My intermittent crashes occur when a 20 pixel wide font accompanies an
RMAIL file with a UTF-8 font in it.  It does not occur with an 18
pixel font.

Today's GNU Emacs CVS snapshot, Sun, 2007 Nov 18  23:51 UTC
GNU Emacs 23.0.50.4 (i686-pc-linux-gnu, GTK+ Version 2.12.1)
started in debugger with

    set args -i -q \
    --eval '(emacs-version t)' -bg DodgerBlue4 -fg white \
    -fn '-Misc-Fixed-Medium-R-Normal--18-120-100-100-C-90-ISO8859-1' \
    -geometry 80x44+660+51 -name '-q GNU Emacs in Debugger 4'

This worked fine on the test file (given below) with an 18 pixel wide
font, but Emacs crashed when I shifted to a 20 pixel font.

(Because I have a high resolution screen and old eyes, I normally use
a 20 pixel font that does not look to me more than 14 actual pixels
high.)

The crash comes on the UTF-8 test file with the 20 pixel font, both
when I shifted from the 18 pixel font and when started a new instance
of Emacs after setting

    set args -i -q \
    --eval '(emacs-version t)' -bg DodgerBlue4 -fg white \
    -fn '-Misc-Fixed-Medium-R-Normal--20-200-75-75-C-100-ISO8859-1' \
    -geometry 80x44+660+51 -name '-q GNU Emacs in Debugger 5'
