New description:

 I noticed that some fonts in firefox-x11 render incorrectly.  I narrowed
 it down to a simple test case:

 {{{
 $ fc-match Fixed
 12x13ja.pcf.gz: "Fixed" "ja"

 $pango-view --font="Fixed" /etc/passwd
 # See garbled cruft in the view

 $  fc-match Fixed:style=Regular
 7x13.pcf.gz: "Fixed" "Regular"

 $pango-view --font="Fixed:Style=Regular" /etc/passwd
 # See an expected render
 }}}

 It looks like we need some logic in the config file to prefer
 style=Regular if no style is designated
