I do think this has been coming up when there has been bad metadata on the system. Recent reports of it show errors like this:

No reports yet with the appstream-glib fix present, so I think continue to watch this and see if any come in with that fix present still. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to appstream-glib in Ubuntu. https://bugs.launchpad.net/bugs/1614105 Title: /usr/lib/x86_64-linux- gnu/fwupd/fwupd:11:as_store_load_yaml_file:as_store_from_file_internal:as_store_load_app_info_file:as_store_load_app_info:as_store_search_app_info Status in appstream-glib package in Ubuntu: Triaged Status in fwupd package in Ubuntu: Triaged Bug description: The Ubuntu Error Tracker has been receiving reports about a problem regarding fwupd.
