Having tried typing "login username" in an rxvt window I can confirm
that the problem exists on NT4 also. "login" is definitely the culprit
and Sergei Okhapkin, in an earlier reply, showed the section of login
code that's responsible.

It's not clear why you are using login when you already have an rxvt
window. I believe it isn't intended as a way of doing an "su username"
but for use by telnetd etc.  If I don't type login in an rxvt window I
don't run into the problem.

Cheers
