As far as I remember, te problem has to do with different font handling
in different devices. I'm sure someone more familiar wiht the internals
will comment on this.

The fix is easy: don't use dev2bitmap but open the desired target device
before plotting. In your case: 

pdf(file='test.pdf', width=6, height=6)
plot(...)
legend(...)
dev.off()
