Somehow, after upgrading some packages this morning, I no longer have
fonts in any gtk apps I've tried (Firefox, Thunderbird, GIMP).
Chromium mostly works, fonts show on web pages, but there are no
visible fonts in the tab titles or in the address bar. Konqueror and
all KDE apps seem to work completely fine.
I've rolled back all of the installed packages, but the problem still
remains. I have tried changing gtk theme, changing fonts, but it makes
no difference. I rebuilt gtk+ (2 and 3) but nothing changed. I don't
know what else to try.
Does anyone have any suggestions or know what might be the cause?
