Hi,
I'm using sqlalchemy 0.9.7 and cx_oracle 5.1.3 and every once in a while
(inconsistent), I get the following error:
Traceback (most recent call last):

I saw several posts about this issue but I didn't find a solution.
Restarting my service seems to fix the issue for a while.
BTW: This error is linked to a mixin class I've created for track-changes
based on the version mixin from
*http://docs.sqlalchemy.org/en/latest/_modules/examples/versioned_history/history_meta.html*
