ECSlidingViewController bound using Xamarin causes crash
I am using a binding project to wrap ECSlidingViewController for use with MonoTouch/Xamarin. I have this setup. However when I attempt to open the menu (by triggering a segue on button click) the app crashes with no error report, nor anything in the application output. All I have to go on is the following crash report I retrieved from the console. Can anyone shed any light on the problem?
The only code being executed is:
// in ViewDidLoad()
menuButton.TouchUpInside += (object sender, EventArgs e) => ToggleMenu();
private void ToggleMenu()
{
PerformSegue("ReturnToMenu", this);
}
The mammoth crash report. I've removed the irrelevant sections and the 20-odd other threads it ilsted.

This is mostly a guess, but it looks like it's hitting a bug inside Xamarin.iOS where we don't generate the proper binding code for Objective-C blocks when those blocks can be null (this has already been filed as a bug here).
If you had a complete test project I can run I'd be able to confirm this quickly.
