[ZODB-Dev] InvalidObjectReference - Attempted to store an object from a foreign database connection

[Andreas Jung]

Hi,

I am bringing this issue here up again because this error is an annoying 
problem when using CMF or Plone
(no idea how they are related to the bug). There also a collector issue 
pending:

   http://collector.zope.org/Zope/1248

Trying to track this down I added some a debug output infront of the 
dump(state) call
in Connection.py, line 418. I can reproduce this error e.g. by clicking 
simultaneously
several on "new Issue" in PCNG. This will create new PCNG Issue instances.
The last  debug output before the dump() call is:

Ok, we have a dict. What are the next steps that I can try to figure out 
which of the items causes this problem?

Thanks,
Andreas
