Comment (by dcf):
Here are other Firefox logs from 4.5-alpha-2-fonts-1. I got the names of
log modules from https://hg.mozilla.org/mozilla-
central/file/636498d041b5/gfx/thebes/gfxPlatform.cpp#l2058.
* attachment:fontlist.log
* attachment:fontinit.log
* attachment:textrun.log
* attachment:textrunui.log
* attachment:cmapdata.log
* textperf.log was empty.
The most interesting one appears to be cmapdata.log:

If I guess at the meaning right, it looks like "Droid Sans Georgian
Regular" is claiming support for lots of code points, including most of
ASCII. Maybe it doesn't actually support those, but Firefox believes it
does, so it doesn't try loading any other fonts.
