Short description of error

Exact steps for others to reproduce the error
Open mouse_actuator.blend, start the game (P) and mouse the mouse.

I get a crash with the following backtrace:

To create the file from scratch all you need is a Mouse Actuator with Look mode linked to a Mouse Sensor with Movement mode.
Note: This only happens in debug mode + crash on asserts. It should be investigated nonetheless.

The assertion seems to be inverted by mistake:

MT_assert(!m_mouse);
const SCA_InputEvent & xevent = m_mouse->GetEventValue(SCA_IInputDevice::KX_MOUSEX);
const SCA_InputEvent & yevent = m_mouse->GetEventValue(SCA_IInputDevice::KX_MOUSEY);

Why would you otherwise assert !m_mouse and still use it in the next lines?

I'll remove the ! and commit.
