Physics crashes when adding rectangles with the touch screen

[carrott]

Sometimes physics crashes when you add a rectangle immediately after selecting the rectangle tool using the touch screen. See the log below.

If you touch the rectangle tool and then touch the canvas right next to the menu bar, about 1/3 of the time physics crashes. When physics crashes it just disappears. Repeatedly touching the rectangle tool followed by the canvas will quickly cause the crash. Using the mouse does not seem to cause a crash.

Physics 11 on build 13.1.0 for XO-4 (build 22) on XO-4 B1 with new tinted touchscreen.
