[ZODB-Dev] zodb wants to import my module?

[Chris Bainbridge]

When I call get_transaction().commit() I sometimes get an ImportError from zodb:

Traceback (most recent call last):
  File "/home/s9734229/Work/prog.py", line 216, in ?
    evolver.evolve()
  File "/amd/nfs/beatty/disk/home/bw1/s9734229/Work/evolve.py", line
254, in evolve
    self.evaluate(eval)
  File "/amd/nfs/beatty/disk/home/bw1/s9734229/Work/evolve.py", line

    get_transaction().commit()
  File "/home/s9734229/root/lib/python2.3/site-packages/transaction/_transaction.py",
line 293, in commit
    self._commitResources(subtransaction)
  File "/home/s9734229/root/lib/python2.3/site-packages/transaction/_transaction.py",
line 340, in _commitResources
    rm.tpc_vote(self)
  File "/home/s9734229/root/lib/python2.3/site-packages/ZODB/Connection.py",
line 983, in tpc_vote
    s = vote(transaction)
  File "/home/s9734229/root/lib/python2.3/site-packages/ZEO/ClientStorage.py",
line 885, in tpc_vote
    return self._check_serials()
  File "/home/s9734229/root/lib/python2.3/site-packages/ZEO/ClientStorage.py",
line 869, in _check_serials
    raise s
ImportError: No module named evolve

Why is this? Is it safe to ignore it?
