Web member list has extra bad characters via email subscribe

[Ptcheezer]

When I subscribe via an email command with a
password, then the user shows up in the memberlist
with extra characters like:
u ' and \

The members who were subscribed using the web
interface mass-subscription do NOT have any extra
characters at all.

The user still gets emails from the list, but when you try
and click on the user in the admin web interface it will
not go to their user page (goes to the General Options
page instead)

Here is the table row from the Mailman admin interface
where you can see the extra characters:

<tr>
      <td><center>u'<INPUT
name="[e-mail]_unsub" type="CHECKBOX"
value="off" >'</center></td>
      <td>u'<a
href="u\'https://lists.some.org/mailman/options/hrep-
agr/amember--at--
ap.org\'">u\'<email address hidden>\'</a><br><INPUT
name="[e-mail]_realname" type="TEXT"
value="" size="23" ><INPUT name="user"
type="HIDDEN"

      <td>u'<center><INPUT

value="on" CHECKED ></center>'</td>
      <td><center>u'<INPUT

      <td><center>u'<INPUT

    </tr>

I can't reproduce this in MM2.1.4a0 (now in cvs).
