+Subject: [PATCH 2/2] check --repair: fix malfunctioning validator, fixes #3444
+
+the major problem was the ('path' in item) expression.
+the dict has bytes-typed keys there, so it never succeeded as it
+looked for a str key. this is a 1.1 regression, 1.0 was fine.
+
+the dict -> StableDict change is just for being more specific,
+the check triggered correctly as StableDict subclasses dict,
+it was just a bit too general.
