Unity does not switch to the correct desktop when an app is "maximized" across dual screen

[Peter De Maeyer]

System:
Natty 32-bit (pae kernel) + NVidia + dual screen

Steps to reproduce:
1. Run an app (for example gedit)
2. Maximize it across both screens (drag it manually as far as you can, don't use the "maximize" button since that will only maximize it on one of the two screens)
3. Switch to another desktop (for example CTRL-ALT-RIGHTARROW)
4. Try to switch back to the already running app by clicking the corresponding icon in the launcher

Expected:
Desktop switches back to the first desktop with app on top

What actually happens:
Nothing, except for a little arrow appearing to the right of the app's icon in the launcher, the desktop does not switch

I tested some other Java apps and they are not affected by this bug, so it's probably not Java related after all...

Dual-screen related, not Java related at all. I updated the description and original steps to reproduce to reflect my latest insights.

Same here with an AMD Radeon HD 6470M using radeon driver.
I'm using Ubuntu Natty x86_64

Are you still experiencing this bug in any current supported Ubuntu release? (https://wiki.ubuntu.com/Releases)

If so please execute the following command in a terminal, as it will automatically gather debugging information:

I don't have access to the dual-screen setup right now. It'll have to wait until beginning of October.

All right, so I will wait here sat for you to come ⛾
