[Zope-dev] ZODB Mountpoint broken?

[Suresh V.]

ZODB Mountpoint distributed with Plone 4.1.2 always seems to create 
OFS.Folder even if the container-class is specified.

Also getting a "KeyError: item already present wih same id" due to 
_setObject and _setOb both being called.

Am trying to mount a plone.app.folder.folder.ATFolder from a separate 
Data.fs using instructions in:
