* A security researcher crafted a gif that would cause the Android Bitmap code to throw an NPE. That would cause messaging to crash when decoding the NPE. Catch the NPE. Test: manually tested the "crash.gif" attached to the bug. Stepped through the debugger to verify we're catching the NPE and logging the attempt. Verified normal gifs still work.
