Zooming is allowed to 150,000,000,000% using the trackpad, and hides/crashes the window.

First of all, if you have any Haxies, InputManagers, SIMBL plugins or
similar operating system hacks installed, please remove them first, restart
the program, and make sure the bug is reproducible without them.

What steps will reproduce the problem?
1. Open image
2. Zoom in (using touchpad)
3. Cry

What is the expected output? What do you see instead?
I expect that the zooming would stop at 3200% as it does with using the zoom 
button, but instead it lets me zoom to approximately 150,000,000,000% before 
crashing the window. The app stays open, but the window goes away.

What version of the product are you using? On what operating system?
v2.2 on OS X
