[Zope] ZCatalog Find Items broken in ZOPE 2.1? (was Very important for CatalogWare zopists)

Hi!
I investigated some more on the find problem and think that the Find Items
option in ZCatalog is broken.
Here is what I did:
- Installed ZOPE 2.1.2 Win32 Release.
- Created a ZCatalog as /Catalog
- Created a DTML Document as /test
- Selected DTML Document in the Find Items
- ZOPE finds the test Document but displays its path as /test (the link
leads to http://test)

*Ouch*

Marcus,

Yeah!
Now I know I'm not going crazy. :)
I don't see any way right now that could cause just a "/" to be inserted
using the ZClass generated code.
