--- Comment #7 from Akira TAGOH tagoh@redhat.com --- That config enforces the scalable font to choose which means you aren't using the attached font actually. you can see:
$ fc-query /path/to/9x15-ISO8859-1.pcf | grep scalable scalable: False(s)
Do you have any other "Fixed Regular" font in your box? what about fc-match -a "Fixed:style=Regular:lang=en" ?
