The error says that some directory in the path
'/var/lib/mailman/locks/somelist.lock.myhost.24422.0' doesn't exist.
Unless either 'somelist' or 'myhost' contains a '/' which shouldn't be
possible, that means one of the directories in the path
'/var/lib/mailman/locks/' which again seems unlikely given that other
lists work.

What is the contents of the '/var/lib/mailman/locks/' directory? If
Mailman is quiet, it should be only master-qrunner and
