[ZODB-Dev] Re: [Zope] HELP - POSKeyError 000000000001efcd -

[I posted to zodb-dev as I was told they were the GURUs and could help
since this is in the ZODB).
What I have tried:
1) Using fsrecover.py (with and without -p and before and after packing)
This has removed data but along with it a lot of data that I need. If you
don't use the -p it removes nothing and I am stuck with the POSKeyError
2) Exporting the folder I think is corrupt (/Members/) and importing it
into a new CMF.
It imports, but the POSKeyError comes with (in a new location)
3) Deleting things out of the folder that could be causing the problem
Gives me lots of errors about not being able to "unindex" the items
followed by a POSKeyError
in debug mode: "ERROR(200) PathIndex Attempt to unindex document with id
Any new direction would be appreciated. The problem with hosing the darn
/Members/ folder is that it has Members stuff in it.
