Bug Description

This is on Precise

STR:
1. Log in to fresh Unity 3D session.
2. Launch gnome-terminal
3. Launch gimp in gnome-terminal
4. Wait for windows to open.
5. Press Control-C in gnome-terminal to terminate gimp.
6. Launch gimp again
7. Open Dash with Windows key or launcher button

Expected results:
Dash should not be confused about crashed applications and should show up in front of all windows

Actual results:
Some gimp windows start appearing in front of dash. Then Alt+Tab to gnome-terminal makes it appear in front of dash and launcher too.

I can't reproduce this issue using those steps. Is it 100% reproducible? If so, can you provide a screencast of the issue? That would be great.

The screencast is at http://www.youtube.com/watch?v=yIpm2bCaoGU - the first interrupting of gimp did not cause the bug to appear but the second attempt broke unity window order.

I haven't seen this at all after the release so that looks like the fix was released.
