Right. I was trying to pinpoint the error by assuming that this
used convert to show the eps file in lyx.
   

Run "lyx -dbg graphics" from the console to see what lyx is doing with 
your images.
 

Thx. That is very interesing. Here is the output. It seems it using 
convert if you look at the shell script.

The crucial points are these.

a) lyx preview does not work. It gives the conversion error I
mentioned in the previous email. b) View->Postscript does not work.
It gives
Error: /undefinedresult in --div--
Operand stack:
  0.0   0
which is the division by zero error I reported last week.
   

So? This is simply saying that the eps file is a pile of junk.

That is really odd. I can't have a buggy imagemagick AND a buggy dvips 
on this standard fedora system can I?  I should note that I can 
"convert" the eps file using redhat 8.0 just fine. So it seems that the 
eps file can't be that bad.  Can you do anything with the latex file I 
sent you by the way?  I think there might have been another 
misunderstanding as well. I am converting the approx-pic latex file to 
an eps to be included in a lyx document.

Sorry if this has been all a bit confused.
