[gnome-core] [repost] strange display with gtk-demo

[dominix <do...@de...>]

every gnome packages installed without problem, but when running the
gtk-demo it look like http://iquebec.ifrance.com/dominix/gtk-demo.JPG
 ... strange (no fonts ?)
my aim is to use gtk2-perl (which compile and install fine) but has the same
display  problem.
what is THE fix for that ? (I suspect fonts.conf but don't know what to do
with)

thank for your time.
