Alt+Print captured by Unity / HUD

[fyo]

Pressing Alt+Print has no effect until release, upon which the HUD is activated. Only then does the screenshot app activate. The result is that the screenshot app takes a picture of the HUD, not the active window.

Thank you for taking the time to report this bug. We have tried to recreate this on the latest release of Ubuntu, but cannot reproduce it. This bug is being marked as Invalid. If you believe the problem to still exist in the latest version of Ubuntu, please comment on why that is the case and change the bug status to NEW.

The Print Screen key is the default key to take a screenshot. Holding Alt beforehand simply shoes the application menu headings.
