bug#2504: 23.0.90; new-frame => "no font backend available."

[David Abrahams]

Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.

Your bug report will be posted to the emacs-pretest-bug@gnu.org mailing list.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

I think MacOS Emacs isn't very resilient to customizations for other
platforms that should be ignored.  For example, my

  default-frame-alist

is 

  ((menu-bar-lines . 1) (font-backend . "xft") (font . "Bitstream Vera Sans 
Mono-10.5") (tool-bar-lines . 0))

But `M-x new-frame' causes emacs to report "no font backend available"
without opening a new window.

BTW, reporting steps to reproduce bugs with emacs -Q seems to be
counterproductive on MacOS, because if I invoke the underlying
executable instead of the .app bundle, several things don't work
properly... and AFAIK there's no way to pass -Q to the .app bundle.

If Emacs crashed, and you have the Emacs process in the gdb debugger,
please include the output from the following gdb commands:
    `bt full' and `xbacktrace'.
If you would like to further debug the crash, please read the file
/Applications/Emacs.app/Contents/Resources/etc/DEBUG for instructions.
