Bug#865434: mtpolicyd: missing dependencies for default configuration

[Michael Kauffmann]

Package: mtpolicyd
Version: 2.02-3
Severity: important

Dear Maintainer,

my first try with mtpolicyd ended with

> Jun 21 13:34:22 bw mtpolicyd[9463]: loading SessionCache Memcached
> Jun 21 13:34:22 bw mtpolicyd[9463]: initializing SessionCache Memcached
> Jun 21 13:34:22 bw mtpolicyd[9419]: error while processing request:
> could not acquire lock for session 24f0.594a59be.54748.0 at
> /usr/share/perl5/Mail/MtPolicyd/SessionCache/Memcached.pm line 35,


As I understand, the default configuration file uses memcached,
but the package dependencies don't require memcached be installed.

(The <Connection memcached> section seems to be silently ignored if memcached isn't present, but

the <SessionCache> section makes use of it.
Commenting it out helped.)

(libcache-memcached-perl suggests memcached, but doesn't require it.)
