Can you switch to using alpha02 to see if you can still reproduce this ?

Marked as fixed.

The fix will be out in alpha03. Thanks.

Is there a possible workaround or way to avoid this issue? My app has intermittent crashes (I'm using alpha 2) with what I assume is the same issue.

I don't think there is really any workaround. We're working on getting alpha03 out soon though. Thanks!
