[Mono-dev] SEGV, unsure of cause

I have caused a segv in Mono. Was working on MonoDevelop, ran my
solution, and boom. I use nothing except System.* classes... a bunch of
AppDomain work and all, but nothing that SHOULD segv.

My project is pretty small and will be open source... right now I'm not
that far into it, so:


Revision #3 exhibits the crash on Feel free to simply check it
out, pop it open in MD, hit build, and you'll have a breaking binary.

At first it looks like a normal type not found, except shortly
following, the segv.

.... much more ... 

Got a SIGSEGV while executing native code. This usually indicates
a fatal error in the mono runtime or one of the native libraries 
used by your application.
