[Rd] unexpected behaviour of expression(sum())

I'm seeing inconsistent symbols from the same expression with the
expr = expression(sum(x, 1, n))
plot(1, main = expr, type = "n")
text(1, 1, expr)
Moreover, the inconsistency is reversed in r-devel compared to R 2.0.1.
In particular, the main label shows a \bigoplus instead of \sum in
r-devel, and the other way round in 2.0.1. demo(plotmath) shows \sum in
Can anyone confirm? Is this intended behaviour (though I can't see how)?
