Unity launcher shows empty space for icon after dragging Chromium icon from the dash

[Alain Kalker]

How to reproduce:
(Fresh installation of Oneiric)
- Install Chromium webbrowser
- Open Dash using hotkey
- Search for Chromium
- Drag its icon onto the Launcher, between other icons

Observed result:
- An empty space appears between the icons
- Clicking on the empty space does launch Chromium
- After launching Chromium, Alt-Tab switching does _not_ show the Chromium icon, so it is not possible to switch back to it after switching to another application

Expected result:
- Chromium icon should appear on Launcher like every other application
- Alt-Tab should allow switching to Chromium like any other application

Workaround: Logging out and back in causes the Chromium icon to appear in the Launcher as it should.

Same here, not depend on application. Minimized windows can't be recovered, *very* annoying.

Oneiric have reached EOL since a while and that issue is not reproducible with recent version(s)
