How to track down OutOfMemory exception on production device?

I've got a user running a device that I don't have access to. All of the devices that I do have access to, do not throw this error.

I've implemented error tracking in the app, and this is what it's reporting.

How do I track this down and solve it?

The user is running Xamarin.Forms 1.2.3 Pre1. Their OS is 4.1.1, and their device is an HTC One s.
