installing new fonts makes emacs unusable

[Paul Scott <paslist@ultrasw.com>]

I installed a bunch of fonts and now emacs (21) is unusable in X on my 
sid system.  All characters show up as squares.  I can't even be sure 
that is what caused the problem.

I have removed most fonts I can find.

Any ideas as to how to diagnose this would be appreciated.

TIA,

Paul Scott
