Crash Data

This bug was filed from the Socorro interface and is 
report bp-0f877abd-4bef-4798-9b2b-fe76f0170420.
=============================================================

21 crashes in the last week on 54 and 55, from 14 installations, so reasonably high volume for Android.
I also see a corresponding, but less frequent issue, where we apparently attempt to register the listener for a second time without having it unregistered some time beforehand. Strangely enough, at a cursory glance the register/unregister calls do seem to be matched up in onPause/onResume of GeckoApp and GeckoPreferences [1], though.

Also, I'm not sure if I've searched correctly [2], but all of the crashes seem to happen in BrowserApp, i.e. I didn't find any stack traces referencing GeckoPreferences/CustomTabsActivity/WebAppActivity.

Bug 1393128 should have fixed this by moving the Snackbar handler to GeckoApplication.
