Silly me, of course I had .PS figures in the document, no wonder there
were PS specials in there...  

So just to test this theory I just went through the document and
commented out all the \includegraphics commands.  I ran
preview-document again and got:

>  dvipng warning: at (1,0) ignored header \special{!/[EMAIL 
> PROTECTED](CVS-1.107)def} 

now, however, preview-latex seems to ignore the warning and happily
uses all the bits and pieces produced by dvipng (at least there is no
trace of dvips+gs running in the log).

I guess what confused me was that (incorrectly, it seems) assumed that
the warnings were what triggered the failure, as they were the last
lines in the log before 
"preview-dvipng [or something similar to that] failed".

Oh well...

Thanks for quick response...
