Obscure crash

I'm not sure if this is just my setup, but if you left click and hold on the viewport option button that is circled on the pic above while still holding the left button hover back over the option button itself and release the left button. The context menu does not disapear. If you click the viewport option button again while the context menu is still there Constructor crashes. I'm guessing it is because the context menu was still there when a new one is being called to get created, because the old one never got deleted.
