bug#1955: 23.0.60; otf font renders, but not when 'default' face is explicitly selected

[Greg Falcon]

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:


(This is with an emacs built from cvsroot on Ubuntu 8.10.  Build
details below.)

I am having only partial success getting emacs to render the otf font
"Inconsolata".  Specifically, the font renders successfully inside
emacs, *except* when displaying the 'default' face, or a face that
explicitly inherits from it.  In that case, the font renders as
rectangles.  For a screenshot, see

  http://verylowsodium.com/faces.png

This seems to happen no matter how I set the default font.  My
standard ~/.emacs sets a font using window-system-default-frame-alist.
But even a simple invocation of

  emacs -Q -fn "-*-Inconsolata-*-*-*-*-16-*-*-*-m-0-iso10646-1"

produces the sort of behavior as in the screenshot.  Note that the
font in the attached screenshot *is* Inconsolata.  It's not that emacs
can't read the font at all; it just doesn't work for the 'default'
face.  Other (non-otf) fonts do not exhibit this behavior.

Trent W. Buck in IRC gave me a few questions and suggestions, the
results of which I will relay here:

Launching emacs with  -fn 'Inconsolata'  or  -fn 'Inconsolata-12' did
not work, responding that the font "is not defined".

'fc-list' does list 'Inconsolata:style=Medium' among the available
fonts, and 'fc-match Inconsolata' responded
  Inconsolata.otf: "Inconsolata" "Medium"

Setting 'Emacs.FontBackend: xft' as an X resource did not have any
effect.

Build details:

All libraries used were from standard Ubuntu 8.10 packages, except for
libotf, which I built from version 0.9.8 sources.

./configure output:

Configured for `x86_64-unknown-linux-gnu'.
