Comment 2 for bug 1347243

I have been doing some more poking at the problem. Using the debugger, I have isolated the problem to:

(Pdb) b /usr/lib/python2.6/site-packages/migrate/versioning/api.py:32
Breakpoint 1 at /usr/lib/python2.6/site-packages/migrate/versioning/api.py:32

(Pdb)

I think I have some very old code:
