They should definitely be handled, one way or another.

`dired-hide-details-mode' makes sense only in a mode derived from Dired mode.

Your suggested fix sounds like the right approach in general, but I think
turning off `dired-hide-details-mode' should somehow be done BEFORE changing to
a mode that is not dired-derived, not afterward.

Can you use `change-major-mode-hook' instead, to do this before changing the
mode?  Is it possible at that point to test whether the target mode is
(derived-mode-p dired-mode)?
