AFAIAC, the fscking rpms are broken! Anyway, check to see if you have this file AND if its uptodate. As a test, rename it so it can be recovered, and then run: #>/usr/bin/pango-querymodules-32 >/etc/pango/pango.modules To regenerate that file with the systems presently installed modules. That fixed me right up. But I still have bad dreams about those borked rpms that don't have the above command as a 'post-install' script. No excuse for that lack. -- Cheers, Gene "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
