Ssl error with offlineimap version 6.6.1 (debian package)

[Leandro Noferini]

Ciao a tutti,

I have an error with the latest offlineimap package from debian (sid): I
think it is an openssl error but I cannot understand its origin so I
will try to ask here.

My imap server is courier with an selfsigned certificate and it worked
fine for many years but some days ago it began to give me this error:

leandro at tricheco:~$ offlineimap -a BBs

Account sync BBs:

What could be the error?
