Looks like an abusive assertion check.
For definite answer, it would be nice to get client traceback too, with packet 
log to that storage.

If loadObject is part of the undo itself, then next_serial is indeed smaller 
than before_tid (we are making the object go "back in time").

Otherwise, it might be another bug.
