I'm not convinced that these are doing the same thing as whatever gets
triggered from the upper-right "me menu".

Action:
  From the "me menu", i choose "My Account", and wait for the dialog to
show up.  then i choose "System Settings".
Result:
   The panel changes to show all system settings.


Close the panel, test from terminal:

Action:
  in gnome-terminal, i run "gnome-control-center user-accounts &", and
wait for the dialog to show up.  Then i run "gnome-control-center"
Result:
  The panel search box appears (in the upper-right) and the user icon
appears double (see attached screenshot).  the system settings do not
show up.

Anyway, i find i can't duplicate the "invalid uninstantiable type"
warning from the terminal using these commands.  But i can reliably
reproduce the problem (once every two tries or so, depending on my
dexterity with the mouse) from the "me menu".

Annoyingly, i note that the gnome-control-center process (when run from
the "me menu" appears to have fully-detached itself from its parent
processes and is now self-orphaned (parented by pid 1).  Processes
launched from the termninal remain properly parented by the invoking
shell.  This self-orphaning means i don't even know which process to
attach to (or how) to auto-connect GDB to things launched through the
panel.  the session architecture is defeating my debugging skillz :/

Anyway, i'm open to more suggestions for how to get you a backtrace, but
using these commands from a terminal emualator doesn't seem to be the
right choice.
