Thanks for reporting this.

I've been investigating the crash and though I've been unable to reproduce, I have a few theories about possible causes.

It looks like it occurred on Android 5.0. Do you have any other information about the conditions at the time of the crash? Device type? When in the application lifecycle?

Fixed in release 1.4.4 on 3/11.
