I see some unhanded exceptions in our logs

@RolandasRazma We'll look into this and see if we can reproduce the exception on our end. Do you have any advice for recreating this locally, or have you only experienced it in production in the wild?

[RolandasRazma]

production only. we have 39 crashes for 37. Everyone on iOS7, 94% iPhone

It looks like this crash is being caused by the issue described here. Unfortunately, Venmo Touch still depends on foursquare networking, which has been languishing for the past year (last commit 11 months ago).

We intend to rewrite the networking layer, hopefully removing the dependency on FSN, in next few months.

As a workaround, do you think it would be possible to catch this exception in your main.m:20?
