Not quite. What he said is that, because the CachedRepository class is
not a Component, you'll have to get access to the environment through
some other means, probably by passing the environment to
CachedRepository.__init__.
But you should *never* instantiate a ComponentManager in Trac. The only
one that should ever exist is the environment.
He also suggested having a look at #7723, where we update the caching
mechanism to work with multiple repositories, and in particular,
introduce an IRepositoryChangeListener, which will probably get an
additional method to notify about revprop changes or something similar
at some point.

Then there's something wrong with the class MantisChangesetQuery. Either
it doesn't inherit from Component, or it isn't initialized correctly.
