I got an e-mail from the 1blu support, asking for my offlineimaprc,
because they were not able to reproduce the error.

I tested it again, and the errors were gone. But, as these folders got
synced, offlineimap "crashed" with an Assertion error:

Curiously, these errors did not happen when syncing to the Hetzner
IMAP-Server, so they must have something to do with the 1blu server and
its settings.

Any hints? I could deliver a IMAP debug output, if needed.
