Natural mock of generic static method in generic type?

The assertion in the below test fails, because the expected call isn't mocked:

TestCase 'Test.TestGenericMock'
failed: TypeMock.VerifyException :
TypeMock Verification: Method OtherClass`1.GetInstance() has 1 more expected calls
at TypeMock.MockManager.Verify()
Test.cs(305,0): at Test.TestGenericMock()

Is there a way to do this?

Thanks! :)
