[Zope] FolderFilter Breaks with Non-Manager?

[Joel Burton]

Evan -- 

I'm testing FolderFilter for a production site. It works fine
when I log in as a Manager, but when I log in with a highly-privileged,
non-Manager account ("Client" role), I don't see folder
content listings -- instead I see teh rendered content.

The Client role has *all* privileges, so it shouldn't be a
permission problem per se, and this happens on a clean install of Zope2.5.1,
so it's not an incompatibility with a local product.

If I trim your __init.py__ file down and comment out the filtering
stuff, I still can't get Folder views -- as long as the Folder.manage_main=
DTMLFile() line is there, this bug happens.

Any advice on where to start looking for this bug? Or any workarounds?

Thanks!
