gtk+ for linux framebuffer crashed

["Dirk Volkmar" <Dirk Volkmar deutsche-boerse com>]

Hi!

I had some problems with the framebuffer version of gtk. Allways I started an
application, eg gtk-demo it crashed with an segmentation fault.
With the stack dump of the core file I discovered that fontconfig has some
problems with the path "/usr/X11R6/lib/X11/fonts/URW". After throwing the path
out of the fonts.conf file gtk-demo worked like expected.
The none framebuffer version of gtk+ worked without changing the fonts.conf.

Has anybody an idea whats the problem is ?
