The panics are gone, it seems this patch fixes the issue. I see in my 
logs normal login and connection closed messages.
I applied this patch to dovecot v2.3.0 and tested it with the Android 
K-9 Mail App. I used the option "Use compression on network", which 
seems to be a default for a new connection.
