This isn't a super elegant solution, but it does work:
Make a new view, call it something descriptive.
Customize the view and set it to Categories.
See the attached screen shot for how to define it. The first category is an expression as shown. The second category is simply the [Year] field.
Once it's displayed, it will be thumbnails. Change the list style to Details.
Now you'll see something like my screen shot. Make sure you can see the Date field as I have shown. Notice that some of the Date fields have the word "avg" at the end, indicating an average. This is because the date is different across files in the album.
So just scroll through the list looking for "avg" in the date field. When you find one, you have an album with multiple Date entries. As I said, not elegant, but it works. If you have thousands of albums, this may be a bit tedious, but probably not too bad.
