Bug Description

Binary package hint: unity

This was a bug before and was fixed in the update a week ago since now you can launch unity by just calling it on the command line. Adding a --replace would just be nice since gnome-panel is called like that and gnome-shell is called like that.

unity (3.2.12-0ubuntu1) natty; urgency=low

  * New upstream release.
   - Window border doesn't get restored (LP: #691812)
   - When a menu is triggered from Alt+key, app name stays visible on panel
     (LP: #691765)
   - show the launcher on <Super> KeyPress, this will be needed when the
     shortcut will be implemented if we are in intellihide mode
   - Make sure an underscore is correctly placed under the corresponding
     accelerator-key. (LP: #683427)
   - Adding a dummy --replace option for compatibility reason (LP: #692569)
   - Compiz crashed with SIGSEGV in CompWindow::id() (LP: #694945)
   - Tooltip text not vertically centered (LP: #697791)
   - Maximizing a window horizontally or vertically removes the title bar
     (LP: #696780)
   - Mousewheel support for indicators (LP: #681428)
   - Avoid Quicklists being positioned so that they are partially offscreen at
     the bottom screen-edge. (LP: #691114)
   - Migrate awn, docky and cairo-dock dock launchers (LP: #692967)
   - Include manpages, and make them translatable. (LP: #684896)
   - Automaximize windows in Unity with some rules like blacklisting some
     applications, initial window size.
     It fixes also some bugs, like maximized window on first map not
     undecorated (LP: #667009, #669716, #693779, #691741)
   - Update libunity to conform to latest GIO VAPI breakage (LP: #679964)
   - Initial unity-atk module implementation (LP: #701680)
   - Panel autohide when on Quicklist (LP: #683261)
  * debian/control:
    - unity breaks on older bamf version (dbus protocol changed)
    - needs latest and greatest from dee
    - add libatk1.0-dev build-dep
  * CMakeList:
    - distro-patch to avoid building tests right now as building them is failing
      with the current vala/gir stack. THIS NEED TO BE REMOVED.
  * debian/rules:
    - don't --fail-missing as we don't want to install the vapi yet. The gir
      package will come next week.
  * debian/unity-common.install:
    - install the manpages
  * debian/libunity3.symbols:
    - updated

I'm using unity 3.8.16-0ubuntu1~natty1 and I don't see --replace in the man page. It does accept the option but I don't see any difference; both with and without, the existing instance crashes with 'Segmentation fault'.

With or without other options, I would expect:
* unity /with/ --replace to quit rather than crash the existing instance, and
* unity /without/ --replace to say it's already running and quit.

Take Compiz for example:
james@james-ThinkPad-X60-Tablet:~$ compiz
compiz (core) - Error: Screen 0 on display ":0.0" already has a window manager; try using the --replace option to replace the current window manager.

I've attached output from the terminal for when a second instance of unity is run. I added space-hash-comment to note when I did something. See lines starting with space-hash (' #').

Hmm, just tried the same thing for compiz --replace. The output is very similar. I know Unity 3D heavily uses Compiz, but I don't know whether the segmentation fault is output from unity or compiz.
