Description

Hi, since we migrated to actor, we've been seeing error's like: "CannotCreateActorException from line 2526 of /srv/mediawiki/w/includes/user/User.php: Cannot create an actor for a usable name that is not an existing user" when importing dumps.

Can this be fixed please?

Encountered a similar issue when running the test cases for the TranslateSvg extension. See the build log for further details - https://integration.wikimedia.org/ci/job/quibble-vendor-mysql-hhvm-docker/45823/console

This looks like it's probably the same problem you already reported as T211450: importDump does not work with actor if the user name is not in canonical form. If that's not the case, please provide the details necessary to differentiate the two.
