[Where problems could occur] TBH this fix is far above my head. Only code comments are changed, i.e. some occurrences of "full" are replaced with "container", but it still has proved to be it. The reasoning in the commit message sounds plausible: https://github.com/ximion/appstream/commit/b52858bf [Original description] I just run the isenkram-lookup command. The crash may be related to this autopkgtest failure (which current blocks migration of gtk+3.0): https://objectstorage.prodstack4-5.canonical.com/v1/AUTH_77e2ada1e7a84929a74ba3b87153c0ac /autopkgtest- hirsute/hirsute/amd64/i/isenkram/20201108_141822_ee8c4@/log.gz This is the script which fails: https://salsa.debian.org/debian/isenkram/-/blob/master/debian/tests /test-command-line and it includes the isenkram-lookup command.
