We're getting a JavaScript error ('null' is null or not an object) when adding (saving) a new page. If you've configured the browser to show JS errors as popups, this is a somewhat annoying error.

The error is caused by the fact that the 'locationShowing' input element isn't on the form when you create a new page. It happens, no matter which theme we use and no matter whether we're using Wysiwyg or not.

We're still using 2.4.5 (haven't upgraded yet), but I guess this also occurs in the newest version, since I couldn't find anything about it in the release notes.
