I’m running Debian 8 (Jessie). Dovecot is version 2.2.13, Dovecot Antispam is 
2.0+20130912-2 and SpamAssassin is 3.4.0. I did not fill a bug but I see you 
already did it.

Here [1] is an old thread about that problem.In short: It seems to be a problem 
in sa-learn that is triggered by the privilege drop that dovecot does when 
starting.

I have the same problem and I have not found a solution yet.
