daily cron job spam about "razor2: razor2 check failed: razor2: razor2 had unknown error during get_server_info"

[Marius Gedminas]

Starting with March 14 I'm getting two or three emails a day that look like this:

From: Cron Daemon <email address hidden>
To: <email address hidden>
Subject: Cron <amavis@fridge> test -e /usr/sbin/amavisd-new-cronjob && /usr/sbin/amavisd-new-cronjob sa-clean

razor2: razor2 check failed: razor2: razor2 had unknown error during get_server_info at
/usr/share/perl5/Mail/SpamAssassin/Plugin/Razor2.pm line 186, <GEN2> line 1. at
/usr/share/perl5/Mail/SpamAssassin/Plugin/Razor2.pm line 329.

The only difference is on the Subject line: sometimes it's sa-clean, and sometimes it's sa-sync.
