### Description

Slowly working my way through troubleshooting a new install. After disabling certificate verfication I can log in and see the list of my profiles, however trying to select a profiles takes a long time to load and fails with a generic ""

Looking at the logs I can see the below Stack Trace:

Start with resources/lib/KodiHelper.py at build_main_menu_listing, where the traceback shows the KeyError, then trace the call from Navigation.py's show_video_lists and router. Confirm how video_list_ids is populated for the selected profile; done means selecting a profile loads and lists its shows instead of failing with KeyError: 'user'.
