Hello,
I upgraded today in the morning to version 7.1.0 and could not sync anymore. The error I
get is:
OfflineIMAP 7.1.0

I tried downgrading to 7.0.14 again, but I get the same error with that version now. I
have no clue what happened here. I did a system update today, so it can also be a python
package that offlineimap depends on (most probably this is the root cause, because 7.0.14
does not work now).

Any hints where to look first?
Cheers
Andreas
