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

---------------
unity (4.24.0-0ubuntu2) oneiric-proposed; urgency=low

  * 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…

unity (4.24.0-0ubuntu1) oneiric-proposed; urgency=low

  * New upstream release and some cherry-pick:
    - compiz crashed with SIGSEGV in PluginClassHandler<UnityWindow,

    - unity panel menus don't stay open when clicked on second monitor
