Windows Phone 8 - WiFi Network Lost - Crash

My app on Windows Phone 8 is crashing if the WiFI network is lost. I created a clean Unity project and reproduced the problem. It appears to be a Unity problem. Has anyone else hit this or know how to fix it?

Repro:

Made a Unity project, enabled networking (you do that for the Windows Store build or in the Exported Visual Studio project).
Export Windows Phone 8 build.
In Visual Studio, set the debug mode to Native Only (project properties->Debug).
Connect the phone to a WiFi network you can kill and delete all the other networks (so there is no failover).
Make sure the phone is connected to your WiFi. Debug/Start app.
Once up, kill the network.
Wait a few seconds for the phone to detect the WiFi network loss.
Notice the crash (if you enable all the exceptions in Vis Studio you can catch the crash).
