Item11375: adding AdminGroup to the AdminGroup kills foswiki

Note before trying to reproduce this error: be prepared having to stop your web server and manually remove "AdminGroup" from the AdminGroup topic again.

I upgraded to Foswiki 1.1.4 and then to LdapContrib 4.32 and this checkin broke my site. Reverting the patch with wget 'http://trac.foswiki.org/changeset/13472/trunk/LdapContrib?format=diff&new=13472' -O- | patch -p2 -R fixed the site.

I modified ListIterator.pm to get a backtrace:
