I could imagine why this happened. but there are no reaons to depend on the
specific fonts in fontconfig, then I said I'm not sure if or how the
langpacks sasisfies the fontconfig's requirements.

that's easy to imagine too... when no fonts installed on the system,
fontconfig will returns no fonts against the request from the applications.
then applications won't work as expected due to that.
I would recommend starting discussion on devel(a)lists.fp.o and get some feedback
there.
