[Zope] The Goblins of Zope

[Patrick Price]

Just my experience to relate; with Zope 2.6.0 compiled from source on 
Solaris 8, last night I created a DTML document which "disappeared". 
Thinking I had not hit 'save', I recreated it and then I saw two DTML 
docs with the same name in the ZMI!  I was able to delete one of them 
and the other remained.  Same object id, no title, no description.. 
 Strange.
