#1024 Lose Topics when go directly to topics URL

[Jeff Peterson]

If I go directly to my list's Topics URL
(http://my.site.com/mailman/admin/scan/topics) the
first time I bring up my web browser, I get the List's
(Scan) Administrator Authentication page. After signing
in, I am redirected to the Admin List's (Scan) Topics
page, but all my topics are gone for my list. I looked
in the list's directory (mailman/lists/<list name>) and
the config.pck file has been changed and no longer
contains my configurations. Luckily, I had a backup
copy of my config.pck file. Is this a known bug? The
losing of the configuration/topics information only
occurs if I am not currently logged in as administrator
and am redirected to the Admin login page.

This just bit me too. It also of course affects people if
the authentication gets triggered in other ways when
visiting that page. I just logged into the front page,
clicked on 'topics', got prompted for auth information again
and discovered all my topics were gone.

An assert to ensure that the topic list is only shrinking by
a maximum of one would be a nice temporary fix - there is no
web ui for growing or shrinking the list dramatically so
this case would indicate a dataloss bug is about to trigger.

Try the attached patch. I believe it will fix the problem.
It should apply as is for 2.1.5 through 2.1.7, and with a
change in line number, back to 2.1.1.
