It could be you're using too old a version of Python? I'm appear to be on Python 2.7.12 as the default that runs nrfutil.
Not sure though - you could ask on the Nordic forums, nrfutil is their tool.
Generally I build on debian-based systems, so something about the Python package in OpenSUSE could be causing you issues?
