ErrorException: Warning: count(): Parameter must be an array or an object that implements Countable

Description

Captured via Sentry when loading the Craft CP. It would seem either $oldNavItems and/or $newNavItems might not be an array or integer in some cases and potentially needs to be more defensive before calling count?
