offlineimap 7.0.3 thread terminated with exception

[akmassey]

I'm getting a thread-related error on offlineimap 7.0.3 that I wasn't getting with offlineimap 7.0.2:

OfflineIMAP 7.0.3

I took a look at the commit 44a8cf3, but I didn't see anything obvious that could have caused this. Then again, I'm not a python programmer.

I reverted to offlineimap 7.0.2 and I can confirm that works without the thread exception on the same configuration files.

The fix is in the next branch. This duplicates #363 but I agree the title of this issue is not specific enough to find it.

Thanks for the report!

To make it simple, we can't use advanced inheritance features like super() if the parents are not new-style classes (explicitely inherit from object).
