Almost certainly a bug in your PDF viewer.  Presumably you are using 
pdftex (the program) as your TeX engine, and that passes the inputted PDF 
code through.  The suggestion is to view the final PDF in Acrobat Reader 
or ghostview, and not viewers based on xpdf.

The problem is not 'pdf' but most likely your broken PDF viewer.  I've 
seen this one a few times.  R 2.8.0 alpha has an option in pdf() to work 
around this particular viewer bug, but do you really want to be using such 
a viewer?

This is not reproducible, or I would have tried it.
