Re: Failed assertion on make-frame-on-display

[Richard Stallman]

    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.
