Do you have any Adobe plugins installed? They are known to be buggy and crash at times. The standard OS X pdf viewers work just fine.

In case you have no plugins - can you, please, describe in detail how to reproduce the issue? (GUI/ command line, exact version) I was following your steps in the GUI [R.app GUI 1.34 (5589) i386-apple-darwin9.8.0] and it was working just fine on 10.6.3 (I don't have access to 10.5 at the moment).

Thanks,
Simon
