This bug report will be sent to the Bug-GNU-Emacs mailing list
and the GNU bug tracker at debbugs.gnu.org.  Please check that
the From: line contains a valid email address.  After a delay of up
to one day, you should receive an acknowledgment at that address.

Please write in English if possible, as the Emacs maintainers
usually do not have translators for other languages.

Please describe exactly what actions triggered the bug, and
the precise symptoms of the bug.  If you can, give a recipe
starting from `emacs -Q':

In stock emacs 24.3, add the following to .emacs

(setq default-frame-alist
  `((font . "-misc-fixed-medium-r-semicondensed-*-13-*-*-*-*-*-*-*")

Start emacs under X, and try to bring up a new frame (C-X 5 2).  Observe the 
Invalid font
conplaint, and note the width is hyphenated contrary the the rules for xlfd 
naming.  This
also fails when starting a window with 'emacsclient -c'.  S. Monnier mentioned 
the bug in the
development list back in November of 2012; what became of this?

Attached is a patch that moves the proper xlfd names to the head of the style 
table entries.
This is definitely in "works for me" territory, but it seems to be doing the 
right thing under X.
How it would behave on other platforms, I've no clue as I've no access to them.

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'.
