Both applications (xpdf 2.03 and grace 5.1.13) seem to work fine, except that all menu entries and buttons show only the underscores indicating hotkeys. Curiously, only one of my 2 machines seems affected. I couldn't get any help in the Forum, and even my efforts to reinstall Gentoo from stage 1 were in vain. Since I'm completely lost I'm filing this as a bug report. Any help is appreciated.

Problem solved: After weeks and weeks of desperate searching, I've found the source of this problem: Removing FontPath /usr/X11R6/lib/X11/fonts/local/ from my XF86Config file brings everything back to normal. Now I'd be really happy to know exactly WHY this solves my problem!?
Apparently you have a broken font in there with the same name as a good font somewhere else.
