Subject: 23.3; font trashes mode-line file name
--text follows this line--
This bug report will be sent to the Free Software Foundation,
not to your local site managers!
Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.

Your report will be posted to the bug-gnu-emacs@gnu.org mailing list
and the gnu.emacs.bug news group, and at http://debbugs.gnu.org.

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':

emacs -q -fn -adobe-times-bold-r-normal--0-0-0-0-p-0-iso8859-15 anyfile

The mode-line display of the file name is trashed. It consists of a
sequence of small narrow empty rectangles. The mode and line number are
legible and not trashed.
This problem did not happen in version 22 of emacs. This font is used
satisfactorily in the mode-line in version 22 of emacs.

If I do an esc-x-list-buffers, then the list of buffers has the
file names trashed similar to the file name in the mode-line.

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'.
For information about debugging Emacs, please read the file
/usr/share/emacs/23.3/etc/DEBUG.
