The proposed version works as expected, no crash happened.
I executed the testcase given by Gord Allott in comment #7. I repeated the steps about 10 times on 3 different installations.

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

    - compiz crashed with SIGSEGV in nux::ROProperty<std::string>::operator
      std::string() (LP: #869109)
    - Dash - horizental divider line in between categories incorrectly drawn
      (LP: #841750)
    - F10 opens a random menu item when it should open the first one
      [regression] (LP: #862849)
    - Switching desktops after using showdesktop can cause hidden windows to

      front (LP: #864708)
    - unity launcher loses track of deja-dup windows (LP: #865051)

    - Double-click on the dash top panel is taken effect on the window
