[Launchpad Bug Tracker <878057@xxxxxxxxxxxxxxxxxx>]

You have been subscribed to a public bug:

When using the "show desktop" keyboard shortcut CTRL+ALT+D, it often
takes two tries to get it to work.

This can be reliably reproduced by going to the desktop with the
shortcut and opening a file from it. This brings all the windows back
(which is a step back in terms of usability from the previous behaviour,
by the way). Afterwards, the user needs to hit the "show desktop"
shortcut twice to get the expected behaviour (hide windows). This may be
due to "show desktop" not realizing that the windows have been already
brought back by opening a file.

The error also occurs after not having used the shortcut before, but I
have yet to figure out what causes it. The whole functionality is
definitely somewhat buggy.
