It is a bug on your system: this is done by cairographics, and I 
suspect that the version you have is broken (or possibly your viewer).
I'll attach the version I get, which does display in italics on my 

I used cairo-1.8.0-1.fc10.x86_64 (on Fedora 10).

And how did you compile it?  This might be a bug in the cairographics 
or fontconfig library used for the CRAN binary build, if you used that 
(and report such issues to R-sig-mac -- see the posting guide).
