I'm seeing a weird intermittent crash in the simulator after calling
GraphRequest() in the Facebook SDK. Has anyone seen anything like
this:

The non-native stack trace is equally unilluminating:
Stacktrace:
at (wrapper managed-to-native)
MonoTouch.UIKit.UIApplication.UIApplicationMain
(int,string[],intptr,intptr) <IL 0x0009f, 0xffffffff>
at MonoTouch.UIKit.UIApplication.Main (string[],string,string)

(object,intptr,intptr,intptr) <IL 0x00050, 0xffffffff>
I'm hoping not to have to sink a bunch of time into isolating a small
reproducible sample that fails, but if no one has seen a crash like
this, my alternatives are limited.
