MMM software is deprecated.
Please consider using something more actively developed like MHA https://code.google.com/p/mysql-master-ha/

I added the following code to /usr/share/perl5/MMM/Monitor/Agent.pm on line 41.

if (! defined($old_state)) { $old_state = 'certinally not new_state'; }

Looking forward to migrating off mmm to corosync/pacemaker.

Can you help with this problem?
