I can still reproduce on current master. Another way to reproduce, which
doesn't involve math, is the following:

(1) Help > Introduction.
(2) Scroll down a bit with the mouse.
(3) Click somewhere.
(4) Press <Alt> + x to open the command buffer.

Sometimes it takes me a few tries. If it doesn't work the first time,
press <Esc> to close the command buffer and start at (2) again.

Can anyone reproduce?
