Oh, yes. I was aware of those. I didn't consider these cases because
those setup are not considered stable, AFAIK.

Also, both distributions don't package imaplib2 and rely on our bundled
version.

Yes. However, you're expected to know what you do. This is of your own
responsability.

Plain true. The more I think about this, the more I'm convinced we
should not provide support when imaplib2 is provided by the system.

In case of a bug, users would be requested to fetch the vanilla
offlineimap and test.
