I don't consider it a proper solution because it fixes the symptom,
not the cause. A different situation may require the buffer-local
variable to be killed when calling `kill-all-local-variables'. What
would you do to fix that?

I wonder if the call to `kill-all-local-variables' is a bit too
sledgehammerish and should be replaced by something less invasive.
