Unable to view tickets when plugin enabled

[steve@…]

I get the following in my log when trying to view any ticket after enabling the MasterTickets plugin and restarting Trac.

17:26:16 Trac[__init__] ERROR: 'NoneType' object is unsubscriptable

Please try updating to the latest trunk.

Works now, fantastic! The only issue I had was pre-existing "blocking" values not being propagated into the "blockedby" of the parent ticket, meaning I had to modify all tickets re-link them.
