Hmm, %d is used by the png backend as an escape sequence that is replaced with 
the actual number later on. The png backend relies on format preserving the 
%d. Of course, we could later on replace \%d by the number, but that's too 
much of a hack for me!

I've now simply remove the replacement of % by \%. gs (at least the pdfwriter 
device) doesn't properly handle files with % in the file name, so this is not 
really a problem in real life.... (plus, the !s placeholder of guile' s format 
also doesn't escape it)

Cheers,
Reinhold
