cairo-dock-unity-bridge crashed with TypeError in on_name_owner_changed(): cannot concatenate 'str' and 'NoneType' objects

Hello and thank you for this bug report!

About this crash, I don't know why 'self.dbus_name' is null but the crash should no longer happen (with the latest revision on BZR)!
I'm going to upload a new version on Quantal (maybe tomorrow) with other fixes. Feel free to test it and report any bugs ;)

PS: You can also use our 'Weekly ppa' (should contain less bugs than your version ;) ): http://glx-dock.org/ww_page.php?p=ppa%20Weekly

Thankyou for fixing :). I switched now to the weekly ppa and it already seems to work better than before :)

This bug was fixed in the package cairo-dock-plug-ins - 3.0.99.beta1.1~20120827~bzr2515-0ubuntu1

---------------
cairo-dock-plug-ins (3.0.99.beta1.1~20120827~bzr2515-0ubuntu1) quantal; urgency=low

  * New upstream snapshot.
  * Upstream ChangeLog (detailed changes):
   - Recent-Events: Dialog: no longer added removed files
      + Dialog: Applications: Used the translated name
      + Recent files: added deleted files to the hashtable to prevent
         useless g_file_test
   - ShowDesktop: fixed a typo (about the coloration in the code)
      + checked if Xrandr extension is available before using it
         (LP: #1040271)
   - CMakeLists.txt: linked each plugin to all libs used by gldi except
      gldi (and not only to a few modules)
   - Dbus: cairo-dock-unity-bridge crashed with TypeError in
      on_name_owner_changed(): cannot concatenate 'str' and 'NoneType'
      objects (LP: #1041558)
   - CMakeLists.txt: Checked gio-2.0 for 'gvfs-integration' even if GMenu
      is not compiled
      + Linked gvfs-integration static library to gio-2.0
   - GMenu: fixed a bug that could provoke a crash if the applet is
      deactivating
      + Used gio to launch the menu entries, so that the event is stored
       in Zeitgeist
   - Dbus: the binary was not linked to libdbusmenu
      + checked if we have dbusmenu and dbusmenu-gtk before adding DBusMenu
       support
   - DBus: cairo-dock-unity-bridge: excluded the current process when
      looking if the script has not already been launched
      + converted grep commands to python commands to not launch 4 processes
       just for that
      + Added 'Unity-Bridge' before all 'print'
      + ps command: print only pid + cmd
  * debian/control:
   - Bump Cairo-Dock versions
