I don't know whether this is the same issue, but many VF files
 insert absurd rules with semi-infinite negative dimensions.
I reported on this before, wondering whether this was some special 
marker used for some obscure purpose.  Of course, it doesn't print
because the dimension is negative, but what is it for, and where does 
it come from?
