expression paste broken in r-devel?

Hi,

The following expression() is silently ignored in r-devel (r50697):

plot(1:10)
text(5, 5, expression(paste("foo ", alpha)))

Am I the only one having this problem? example(plotmath) runs but all
constructs of the form expression(paste()) do not show up in the
plots.

It's working for me in r50697 in Windows.  Please post sessionInfo, etc.
