How can I find out, which objects are really involved in the conflict.

from ZODB.utils import p64
print app._p_jar[p64(some_oid)]

The oid is available from the traceback. If you are running ZEO it might
be necessary to replace 'app' with the top-level (or some other object)
of the related storage (might be tricky to figure out if you have
multiple storages).

Another trick that helped me lately to identify the reason for conflict errors was to implement the _p_resolveConflict() hook as method of the related class having the conflict.

How would I do that for the Class _IOBTree, which is in a c-module ?
