Presentation exhibiting the bug

Consider the attached presentation, with 5 slide masters. Open it and switch to Slide Master view.

Page Down problem
-------------------

Click the first master (no. 1).

Now, repeatedly, press the Page Down key on your keyboard, and note the order of masters. 

Expected order:  1 -> 2 -> 3 -> 4 -> 5
Actual order:    1 -> 2 -> 4 -> 2 -> 4 -> 2 -> 4 ....

WTF??

---

On master slide 1 - the Page Up key does nothing, which is as it should be.
On master slide 2, 4, 5 - the Page Up key doesn't move us up.
On master slide 3 - the Page Up key moves us to master slide 1.

WTF???

Smaller presentation exhibiting the bug - no PgUp/PgDn movement

I was trying to slim down the exemplifying presentation, but when I did - PgDn and PgUp stopped responding completely. Which is "fine" as a manifestion of the bug, so perhaps prefer this attachment.

Well, I avoid doing that before others reproduce. And - you said you haven't...
