Several errors of objc2_analyzer.py

[mnrkbys]

I am testing objc2_analyzer.py against the following malware sample.
SHA256: 8db4f17abc49da9dae124f5bf583d0645510765a6f7256d264c82c2b25becf8b

However, errors will be occurred like below:

ERROR:flare_emu:exception in _guidedHook @0002DB95: 'int' object is not subscriptable

This script calls flare-emu's EmuHelper.getIDBString() but getIDBString is not implemented.
Perhaps this is a flare-emu's issue?
