Bug: after loading a 1.5mb image on OS X 10.11 Beta, scrolling in the image viewer causes it to crash.
EDIT: Turns out not loading an image and just trying to scroll with the trackpad (two finger scroll) on the image viewer window causes it to crash. Normal scroll bars actually work.

We can reproduce this bug on other Versions of OS X (e.g. OS X 10.9). As soon we scroll with trackpad ImagePlay crashes. Independent of if a file is loaded or not.
