It's definitely related to the Android HD (tablet) version and specific to TSR... I've got 3 phones and 2 tablets here of various versions and running on different devices...
Android (regular) 2.4.13 works fine on all devices (both tablet and phone)
Android HD (phone) 4.0 beta 1 works as expected
Android HD (tablet) 1.2.2 has the two null posts issue
I'll poke around a bit more over the weekend but for now I've rolled back to the previous version of the plugin.
