Since I'm not using the Parcel class in my code anywhere, it must be caused by some 3rd party library. In this case, the only 3rd party library being used is this project.

Also, this will only happen if several applications are running and the offending application has been in the background and is brought back from the background.

The offending code must be somewhere around here: https://github.com/Cheesebaron/SlidingUpPanel/blob/master/src/SlidingUpPanel/SlidingUpPanelLayout.cs#L902
