Are you using sessions? Perhaps this is caused by storing a reference to
a persistent object that is stored in the main database in the session?
I'm not sure if that is bad or not, but I've never tried it. It seems
like it might cause an error like this if there was a reference to the
object from a BTree in the main database and also a reference from the
transient storage and both were loaded.
