mock.patch prevent nosetest from discovering test generator method

Using Mock 0.8.0 and Nose 1.1.2:

test.py:

import mock

import useless_module

class TestClass:

    def check_call(self, number, result):
        assert result == number * 3

    @mock.patch("useless_module.SomeClass")
    def test_method(self, mock_someclass):
        for i in range(3):
            result = i * 3
            yield self.check_call, i, result

useless_module.py:

class SomeClass:
    def return_something():
        raise

When running `nosetests test.py`, here's the output:

% nosetests test.py
.
----------------------------------------------------------------------
Ran 1 test in 0.001s

OK

Obviously, the test is not running the test generator. When I remove the patch, 
it works fine:

% nosetests test.py          
...
----------------------------------------------------------------------
Ran 3 tests in 0.001s

OK

I attached the reproducible code.
