Hello Triblade,
After further testing we where able to find a device and set of steps to reproduce this issue on our end. I have written up a report (UE-27685) and I have submitted it to the developers for further information. I will provide updates with any pertinent information as it becomes available. I do not currently have a workaround for this issue at this time. Once again thank you for you all of the information and time you have given to resolve this issue.
Device Reproduced on:
Lenovo S939 on Android 4.4.2. (This is the one that we were able to reproduce the crash on)
Make it a great day
