I think $this should be $q here and on 536.

I think both of those comments might be related (first one causing the second). Can you run those tests again with that model fix I pushed?

Still getting the exact same results. Do you have PHPUnit, and can you try running the tests via phpunit.phar tests/ModelTest.php? I'm also getting an error in the ExtendedModel test too:

$ phpunit.phar tests/ExtendedModelTest.php
