I have tested this on my Disco development machine, and here's what I found.
Using an iPhone SE running IOS 12.1.2.
Connected the phone using a real cable (using my third party cable only allowed me to charge).
Without doing anything further I open Nautilus and browsed to the phone, and indeed I did see the error described... "unhandled lock down".
However, on the phone itself I was being asked if I wanted to "Trust this computer". I said "Trust this computer" and was then asked to enter my PIN. Once I had done this I was able to browse the photos as expected.
Could people reporting this problem please check that the iDevice has been told to trust the computer and comment here?
