Crash: View Rotate Spin in Orthographic views (ortho.->persp.)

It's best to try this after a fresh start of the program.
Turn on 'View Rotate Spin'
Alt+LMB Click&Hold outside the circle in any orthographic view (left, right, top, front etc.)
While holding ALT+LMB, click the Shift key to snap out of orthographic and into perspective view.
Either right away hit shift again, or release all the keys and then try again to snap into orthographic view with ALT+LMB+Shift.
NVil crashes.
