Scrolling on OSX Crashes GUI

Problem is described well here:

Appears to be related to OSX two-finger scrolling. Going to ignore for the time being (primarily for use on windows anyway). This is almost certainly due to a homebrew configuration.

Error generated on crash:
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xff in position 0: invalid start byte
