Bug description:
[Impact]
An attempt to run the isenkram-lookup command from the isenkram-cli
package results in a segfault/crash. The proposed appstream upload in
<https://launchpad.net/~gunnarhj/+archive/ubuntu/appstream> fixes the
issue.
[Test case]
1. Install the isenkram package
2. Run the isenkram-lookup command
-> Find that it segfaults
3. Install the packages built by the appstream source
package from groovy-proposed
-> Find that the command succeeds and possibly lists a few
suggested packages.
[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:

[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.
