Crash on small number of android devices

[battlebottle]

We've had reports of our app failing to launch on a small number of android devices and Google Play Crash reports suggests it's caused by this module. The two devices are a Galaxy Rugby running Android 4.1 and a Samsung Galaxy Stratosphere2 also running 4.1.

Here's the stack trace:

The error seems to originate in the processProperties method and involves an attempt to cast a String as a android.text.Spannable

At the moment I can't reproduce this on a device I have access to so it's not easy to provide more info right now. Any thoughts on what could be causing this?
