sure that this is related to the new setuptools version.

Control: retitle -1 python-gnupg: test_gnupg.GPGTestCase.test_list_keys_after_generation is flaky
Control: severity -1 normal

(https://ci.debian.net/packages/p/python-gnupg/testing/amd64/75067238/).
I think it must just be slightly flaky, but I didn't find any other
occurrences of this failure from a quick look through the history, so it
must be fairly rare.
