I can view it fine with several versions of acroread, xpdf, kpdf and evince (all on Linux).  But you don't seem to be the first one to have encountered that error...  In theory, the problem could be either with the PDF format (as generated by PDF::API2), or with the the viewer software, which might well have some subtle bug.  I'm afraid I can't help more.  Maybe try a different viewer?
