Public bug reported:

My system's been up for a while, and I haven't seen this bug before.
When I opened up my Lenovo X220 this morning, most of the icons
on the left hand side of the screen have been duplicated.

Here is the order of icons currently shown on the left of my desktop,
with a ">" if the running indication is shown, and a "<" if a "current window" 
indication is shown.

> Dash Home
Home Folder
Ubuntu Software Centre
> Google Chrome <
> gray question-mark (9term terminal emulator)
> gray question-mark (acme editor)
> Konversation
> Spotify
> Update Manager (21)
> Files (same as "Home Folder")
> Update Manager (21)
> Spotify
> Konversation
> gray question-mark (9term terminal emulator)
> gray question-mark (acme editor)
> Google Chrome <
Workspace Switcher
Rubbish Bin

All icons remain responsive apart from the upper two gray question-marks
(9term and acme - their lower icons work fine).

I'm running Ubuntu 11.10 using Unity 3D

There is only one copy of each process still running:
