Public bug reported:

These steps systematically reproduce the issue:
1. make sure you have some application window on the foreground (e.g. Google Chrome)
2. hit Shift+PrintScreen to take a partial screenshot
3. Select the area for the screenshot by clicking and dragging
4. (IMPORTANT) Use the dropdown selector to choose a location other than the default for choosing the folder to save the screenshot to (if you skip this step you won't reproduce the issue)
5. hit Ok
=> the screenshot is saved and the Screenshot application is closed
6. Hit Ctrl+Super+D (repeat several times if you like)

Expedted behavior: after step 5 focus should be returned to the
application that had it before you took the screenshot. And most
importantly, whether or not this happens, step 6 should show desktop

Observed behavior: after step 5 the application on the foreground has
lost focus, and  at step 6 Ctrl+Super+D does nothing


Note that even if it's the Screenshot application triggering the issue, either Xorg or Unity, or whatever piece of software is responsible for keyboard shortcuts and for showing the Desktop, MUST guarantee that (i) keyboard shortcuts always work and (ii) show desktop always work. So, no matter whether or not the Screenshot application is doing something wrong, the mere fact that a buggy (or malicious) application can prevent Show Desktop from working as expected represents a bug in the piece of software responsible of keyboard shortcuts or of the Show Desktop action (whichever of them is failing).

The Screenshot application probably has a bug in that it fails to return
focus to the application which had it, but again, this should not
prevent the Show Desktop shortcut from working.
