Dialog window missing where to save the image

Since recent updates gnome-screenshot doesn't present a dialog window where to save an image. (video)
Make screenshots with alt or alt+print, instead of presenting a dialog images are deliberately saved in 'pictures' folder.
Not a good idea since 'pictures' folder may incl. images to display on unity-greeter.

## Unsure if the culprit is gnome-screenshot itself or some other updates like nautilus, gir or else. Rather wait for triage.
