Title:
  New apps on the launcher have no shortcut key until something is being
  closed

Status in Unity:

Status in “unity” package in Ubuntu:

Status in “unity” source package in Precise:

Bug description:
  Binary package hint: unity

  For certain applications, such as evince and gedit, if they are the
  last application on the launcher, they do not have a shortcut key
  associated with them (such as Super+0, Super+1, etc). This affects
  both the display and the input: the shortcut will not show if you hold
  down Super, nor will it work if you press it.

  The steps to reproduce this are quite specific, but I can always reproduce it on multiple machines. The conditions required to trigger this bug appear to be:
  - The app is in a certain set, which I haven't yet determined, but it includes evince and gedit.
  - The app is in the last position on the launcher (not including the workspaces, apps, files and trash).
  - No other apps have been closed since this app was opened.
  Obviously this is to be expected if there are more than 10 apps on the launcher, but this happens with less than 10.

  Therefore, example steps to reproduce are:
  1. Ensure there are less than 9 icons open on the launcher.
  2. Open Evince.
  3. Do not open or close anything else.
  4. Hold down Super. Notice that the Evince icon has not been assigned a number.
  5. Press Super+n where n is the number you were expecting Evince to be assigned. Notice that it does not do anything.

  The fact that evince was doing it led me to bug #768900 (possibly
  caused by NoDisplay=True), but that doesn't explain gedit.

  A workaround is to open and close something small like Calculator
  after opening Evince or Gedit.

  I would attach a screenshot but PrintScreen doesn't work while Super
  is held down. Is there any way to do this?
