A breakpoint in this area is triggered 4 times before the Emacs frame
appears, then once more after the frame appears. It crashes on the 5th
time.

The 5 values of filename are:
/usr/openwin/lib/X11/fonts/75dpi/courR14.pcf.Z
/usr/openwin/lib/X11/fonts/75dpi/courR14.pcf.Z
/usr/openwin/lib/X11/fonts/75dpi/courO14.pcf.Z
/usr/openwin/lib/X11/fonts/75dpi/courR14.pcf.Z
/usr/openwin/lib/X11/fonts/100dpi/courB10.pcf.Z

"index" is always 0.

"xftfont" is always 0 (perhaps I am printing it wrong? I use "pp".)

I didn't check them all, but these work:

-*-FreeMono-normal-normal-normal-*-*-*-*-*-m-0-iso10646-1
-monotype-Times New-Roman-normal-normal-normal-*-*-*-*-*-*-0-iso10646-1

These are both TrueType fonts. I did not find any of the fonts in the
75dpi directory that worked (but it was not an exhaustive search).
