ValidationError { instance: Null, kind: Type { kind: Single(String) }, instance_path: JSONPointer([Property("root"), Property("sshPublicKey")]), schema_path: JSONPointer([Keyword("properties"), Property("root"), Keyword("properties"), Property("sshPublicKey"), Keyword("type")]) }

Which is hard to read but does point to the invalid profile bits:
`"sshPublicKey": null`, `"encryptionPassword": null`.

BTW that profile is just the output of `agama config show`.

actually localization::settings::LocalizationSettings

Same issue as in #712:

zbus-xmlgen generates a proxy for setting a writable property but
forgets to mark it as a property, generating a method call instead

(I fixed zbus-xmlgen in August but they haven't released a crate since June)

include names of files that were not found

Before, "foo@#$%" was parsed as "foo"

Also make the Regex more readable with (?x) verbose syntax
