evince pdf viewing

It was pointed out to me that scatter plots made on our rhel5 system  
(sessionInfo() below, have the curious
feature that when made with pdf() and viewed with evince show the  
points as "q" not "o".  Is this a known
problem with evince?  It is pretty clearly not a problem with R, since  
if I bring the pdf file back to my mac
and open in acrobat it looks normal.  So this is a just-in-case- 
someone-else-runs-into-this kind of post.
