I see this crash frequently (started wrapping it in a try/catch); but if you do RLV.scrollToIndex(x) it can frequently crash when the component is still being internally setup. (From my point of view and NS's point of view the ._android exists; but apparently internally you aren't fully configured and this should get fixed so that it doesn't crash...
