Here's one suggestion, though I don't know how useful it is: if it's
possible to run the same or similar version of pgg in Emacs 22, you
could and see if it appears there.  If not, we could narrow the problem
down to a change in Emacs' process code during Emacs 23 (though OTOH I
don't know of any that could lead to this).
