I can reproduce this. The actual error appears to be:

Is it intentional that importing a revocation certificate, apparently
successfully (or at least there are no obvious error/warning messages),
is now exiting with status 2?

The failing test script is:
https://sources.debian.org/src/ostree/2024.8-1/tests/test-remote-gpg-list-keys.sh/
and the test keys and revoation certificate can be found in:
https://sources.debian.org/src/ostree/2024.8-1/tests/gpghome/
