A "failed" thumbnail is saved, as per the spec.
The failed thumbnail stores the original mtime, so that system knows
when to re-attempt thumbnailing. But since the ctime is not stored,
permission fixing will not trigger a re-thumbnailing.
It's a valid use case, in other words :-)
Adding the ctime to the failed thumbnail would eliminate this problem in
a backward-compatible way.
