error if reading web archive while changing address

[Smr99]

I triggered a bug in the mailing list software, Mailman.

I was reading the insight-developers mailing list
archives
(http://www.itk.org/mailman/listinfo/insight-developers)
 via the web, logged in with my old email address,
<email address hidden>. While I was doing that, I
updated my email to this one,
<email address hidden>. After responding positively to the
confirmatory email, I went back to
reading the archives in the *same* browser session,
resulting in an error page (below).

Once I cleared my cookie cache, all is well again.

Cheers,
-Steve
