Fix crash when encountering an InterpreterException in a predicate in logging or input Framework.

Browse source 
Inputframework: did not contain any error handling for this case.

Logging framework: tried to catch the interpreter-exception. However the exception already was caught
by the call-function and not propagated. Instead, call returns a 0-pointer in this case, which
lead to a segmentation fault.
