Dock + window menus unresponsive after attempting to do an area screenshot

[Trygve Brox]

Reproduced this issue several times, but it doesn't happen all the time.
After trying to take a screenshot of an area, the screenshotting may fail and the ubuntu dock and all window menus become unresponsive. Mouseover on the dock will change the cursor to the plus-sign used when selecting the area to screenshot, but nothing happens if you try to click or click/drag.
Shift+Print Screen will allow you to try to click/drag and the pointer stops becoming a plus-sign after this, but the dock and menus are still unresponsive.
Alt+F2 & r seems to resolve the issue.
