Trac 1.2 fails with MWP 1.4.0

[trac@…]

After upgrading to Trac 1.2 and MWP to 1.4.0 (trunk version as of today), it throws:

Cannot find implementation(s) of the ITicketActionController interface named MultipleWorkflowPlugin. Please check that the Component is enabled or update the option [ticket] workflow in trac.ini.

Additionally, on the same error page:

• Error with navigation contributor "AdminModule"
• Error with navigation contributor "SearchModule"
• Error with navigation contributor "RoadmapModule"
• Error with navigation contributor "QueryModule"
• Error with navigation contributor "ReportModule"
• Error with navigation contributor "TicketModule"
• Error with navigation contributor "TimelineModule"
• Error with navigation contributor "BrowserModule"
• Error with navigation contributor "WikiModule"
• Error with navigation contributor "TracHoursPlugin"

Apparently I found it: __init__.py was changed at revision [16598] from:

    pkg_resources.require('Trac > 1.0')

to

    pkg_resources.require('Trac > 1.2')

Running the plugin at 1.2, it did not accept it.

I hacked it to

    pkg_resources.require('Trac > 1.1')

and it works now in my 1.2.
