Pallet crashes on launch

[1-61803]

I tried compiling it on OS X 10.8.5, Xcode 5.1.1. I cloned the repo and only changed target and SDK to 10.8 and manually moved the framework to ~/Library/Frameworks/. Latest commit as of now: [b40c6f7435ec02c4a2306713e6780d3baaab9e27/pallet].

Here's a snippet of the crash report.
