Not sure how this happened; maybe the spinner when pulling to refresh? Maybe icons loading?

Steph's going to look at this, see if there's anything we're doing that should terrify us. Mark tracking with your findings, Steph! :D

Looks like this error is coming from SDWebImage's image decoder. See https://github.com/rs/SDWebImage/issues/1203. 

I've added a temporary workaround that was suggested in that thread for now until a new version of the library is released.

I don't know the actual consequences of this bug but we should probably patch it for now.

They've updated master to include a fix for this. I've updated the Cartfile to pull in the latest changes.
