Having said that, I'd very much welcome your patch which would add this (and couple of more) test cases with odd invalid input to make this more robust.

File osmopy/osmo_ipa.py:

PS2, Line 126:         if (int(length) != 0):
> Sorry I meant an empty IPA payload. […]
That's only possible if you specifically craft such message using some non-osmocom tool. Which certainly is possible but there're dozens of places where we don't check for that. Making this tolerant to malicious input would be nice but is definitely outside of the scope for this patch. In case of osmocom routines length = len(payload) + 1 and payload is always non-empty string of at least 6 bytes.
