ofEasyCam::disableMouseInput has error on OF0.9RC

This is a bug report.

I tried to use OF0.9RC on Visual Studio 2015.
When I called disableMouseInput() of ofEasyCam function in the mouseDragged Function of OF, an error happened.

Maybe, in the function,
ofRemoveListener(events->mouseDragged, this, &ofEasyCam::mouseDragged);
made an error such as segmentation fault.
