Never say never :) There are legitimate cases for catching an 
Error or even a Throwable (for example, error propagation in a 
multi-threaded environment). However, this is not one of such 
cases.

helxi, an AssertError means there's a problem with your code, it 
needs to be dealt with by fixing the code, not swallowing the 
Error.
