If anyone else is reading this, how I worked around this issue. The page in question had an "activate" method that took two parameters. Depending on page context, it's sister "passivate" method would sometimes return null for one of the array parameters. I made sure this never happened by checking the parameters for null in onPassivate and adding string markers instead.
