I had a crash in my iPad app, and looking through Xcode's crash logs, I see that the crash appears to be happening in the compiled code of the Hue framework.

Any idea what this might be?

__64+[PHBridgeResourcesWriter writeBridgeResourcesCache:nsErrorPtr:]_block_invoke + 34

I'm using the latest code checked into github, i.e. v1.11.3beta with the last commit on Wed Oct 5 17:45:51 2016 +0200.
