Indeed.

I've gotten that before as a result of a compiler bug... I had an 
abstract method that wasn't implemented but the compile time 
error got swallowed by a bug and thus the null method made its 
way to the binary.

I think that bug was fixed.... but still you might want to check 
your code for the `abstract` keyword and ensure they are legit 
implemented in your cases.
