The Book of Unwritten Tales 2 Early access - same backtrace

The same happens when changing the graphics quality setting in "The Book of
Unwritten Tales 2" Early Access (for kickstarter backers). Interestingly with
the mesa debug build it works sometimes(?), but when changing the settings a
few times, it very quickly crashes.
