[MonoTouch] Object reference not set exception when calling UIView.Animate

[DMennis]

I think its a problem with 5.2.9 release of MonoTouch from 3/16. I'm getting
the same error as technohead but a different situation. I can reproduce this
on an iPad 3rd gen (iOS 5.1) and iPhone 4S (iOS 5.01) and in the simulator
for both iPad and iPhone. Rolf, check out the code from my buddy @Tron5000 
http://spinningtheweb.blogspot.com/2011/08/custom-animations-for.html here .
>From this code, you'll be able to reproduce the error we are seeing. My
error below is when I'm moving between controllers with a *custom
animation*.
