Who or what is "gconf"?  If that is what is actually used then
it is neither an email address or the keyid.  I suggest as your
first step replacing "rconf" with the actual key-id (number) you
want to encrypt for to see if that works. It is just that GnuPG
seems to be having problems with the supplied user name.  If
rconf was meant to be an email address either it doesn't match
that field completely or maybe you had a define in your
~/.gnupg/gpg.conf that is now missing.

We can go from there if this doesn't work.
