undefined color: black

[Bob Weiler]

I'm unable to start emacs on a Fedora Core 5 x86_64 install running with 
the rpm.livna.net Nvidia driver. I get 'underfined color: black' and 
similar messages about undefined colors if I try xemacs. 'emacs -nw' 
works fine. Has anybody seen this problem? If so, do you know how to fix 
it?

thanks in advance
