automated theme check says many templates are missing (but they are not)

[den232]

I have an unmodified Dawn theme, but the theme check complains and then dies

22 files inspected, 23 offenses detected, 22 offenses auto-correctable
X An unexpected error occured.

Sample error message:

error: MissingRequiredTemplateFiles: 'templates/search.liquid' or 'templates/search.json' is missing.
