TaskListPlugin - Not working in Trac 12

[CM]

I opened a ticket in trac-hacks about a month ago - http://trac-hacks.org/ticket/6336

Since upgrading to Trac 12, TaskList is no longer working. It maybe
something I've caused but I'm at a loss where to look.

AttributeError: 'list' object has no attribute 'items'

It looks like the plugin is using the Query class, which has changed in
0.12 for OR clauses. Before the change, constraints was a dict, and now
it's a list of dicts. The plugin will have to be adapted for that.

See here for the full story:

http://trac.edgewall.org/ticket/2647

I haven't looked at the plugin, but you might get away with replacing
"constraints" with "constraints[0]" at every location where the error
pops up, depending on how the query is constructed.
