This is a problem that has no easy solution.  I usually end up writing a
script that manually traverses the ZODB and pins it down.  It's always a
real pain in the ass.  One of the problems here is that the piece of code
that shows the error gives you no clue as to what object is failing to be
imported.  If you could get the objectid, it would be easier; but still a
pain in the ass.  Sorry I don't have better news.

This is probably due to the help system (which I affectionately call the
"hurt system" at times like this).  You should try to upgrade to 2.3 beta 3
and see if the problem disappears.
