Thank you for taking the time to report this bug and helping to make Ubuntu better. Please answer these questions:
1. Is this reproducible?
2. If so, what specific steps should we take to recreate this bug? Be as detailed as possible.
This will help us to find and resolve the problem.

I've tried to reproduce but it only freezes, and does not crash.

Hello Konstantin, or anyone else affected,

Accepted unity into oneiric-proposed, the package will build now and be available in a few hours. Please test and give feedback here. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you in advance!

I tested the proposed version and it works.

I executed: sleep 10 && killall -9 gedit
, then minimized gedit. In 10 seconds gedit was gone.

One minor thing: I had Thunderbird minimized that time and its window got restored from minimized state at the same time when gedit died. As if I had clicked on the launcher icon to bring back the window to the desktop.

This bug was fixed in the package unity - 4.24.0-0ubuntu2

* Cherry-pick upstream:
- SRU0-Regression: scrollbar displacement caused dash rows to show less
icons (LP: #875023)
- Really reverts the UI change that was still uploaded even if we had
reverted it...
