Yeah, okay, nailed it. Here's the deal.
THIS Permalink (don't move, just zoom in and out), will generate exceptions.

THIS one (again, just zoom in and out), won't.

It's the same location, but in the one where the exception is thrown, the landmarks layer is turned on.
When Waze enabled addresses for landmarks a week or so back:
* All landmarks by default appear to have a cityID of (null).
* When the landmarks layer is turned on, landmarks are polled for their cityIDs.
* There is no error checking for the condition in which (null) is the city ID (it really should be ignored), so an error happens, and now you have to re-zoom, or reload the page to edit.
