Subject: Failed assertion on make-frame-on-display
X-Spam-Status: No, score=0.0 required=5.0 tests=none autolearn=failed
version=3.0.4
I can trigger the following assertion by running
emacs -Q -fn "-*-terminus-medium-r-*-*-16-*-*-*-*-*-*-1"
and M-x make-frame-on-display to a display that doesn't have that font
installed. When compiled without assertions, emacs dies when
dereferencing the NULL returned by choose_face_font.

I can't test this, but probably the way to fix this is to make it an
error to try to make a frame on a display that doesn't support the
default font; i.e., x-create-frame should try to load the default font
on the new display if it is not already loaded, and do an Ferror if
the load fails.
WDYT?

I can't think of anything better, and it is certainly better than
crashing. So please do it.

I've checked in a fix. Emacs won't crash anymore (and trying to make
a frame on a display that doesn't support the default font raises a
Lisp error.)
