gnus crashes X on foreign characters

[jmv]

I am using Fedora Core 4 with Gnus 5.10.7 and XEmacs.

Whenever I get a spam email that has foreign characters and try to show
it
in the Summary buffer then X crashes and takes everything down with it.

The Xorg.0.log says

Fatal server error:
Caught signal 11.  Server aborting

and there are no more hints.

Does anyone know how I can make Gnus stop trying to display foreign
characters?

BTW, it didn't crash on FC3. I guess it is a font issue.

Thanks
