It doesn't seem to be coming from nx-libs. Note how the code in nx-libs spells "could" in lowercase, but the message spells it with a capital letter. I'm using nx-libs without any problems on a system having =x11-libs/libXfont-1.5.1. Please try to make sure that the following packages are all installed (and correctly installed! If in doubt, reinstall): media-fonts/font-alias media-fonts/font-arabic-misc media-fonts/font-cursor-misc media-fonts/font-daewoo-misc media-fonts/font-dec-misc media-fonts/font-isas-misc media-fonts/font-jis-misc media-fonts/font-micro-misc media-fonts/font-misc-misc media-fonts/font-mutt-misc media-fonts/font-schumacher-misc media-fonts/font-sony-misc media-fonts/font-sun-misc Next thing to consider is your DPI. Do you use any "weird" DPI value? I don't think that's it either, but try setting it to 75 or 95 for testing purposes. How proficient are you with debugging? Or is there any way to allow access to one affected machine? I'd like to get a gdb backtrace of the moment the FatalError() function triggers, to see which library or part *really* is responsible for that message. This will also involve building nx-libs with debug symbols, of course. Mihai
