I want to investigate this before 2.0, so adding to the blocker list.

Test case

I'm attaching a test case that can trigger the crash (actually not the same assertion but the root cause is the same). The problem is that in most cases we don't check incoming method call signatures, and there's code that assumes that such checking has been done.
