network.request throws exception on Android

When attempting to download an image, a native android exception is thrown - the lua callback function is never invoked.

network.request( "http://docs.coronalabs.com/images/simulator/image-mask-base2.png", "GET", networkListener, params )

Unfortunately, I've only been able to reproduce this in my own app. Even then, only after a short time (seconds) after app launch does the issue begin to occur. It's not clear what changes result in this error state.
