[Bug 1433013] Re: Super -> exec vs Alt-F2 -> exec have different environment

[Marco Trevisan (Treviño)]

** Description changed:

  upstart in user session manages environmental variables and most things
- have them, however Alt-f2 started proccesses lack them.
+ have them, however Alt-f2 started processes lack them.
  
- to test
+ [Impact]
+ Some environment variables are missing from apps that are launcher from Alt+f2 command lens, or in general with dbus-activation (an example might be gnome-terminal, global menu not working).
  
+ [Test case]
  Super Key -> "xterm" -> Enter -> env | grep SSH
  
- vs
+ it should return something like:
+ SSH_AUTH_SOCK=/run/user/$UID/keyring-<random-stuff>/ssh
  
  Alt+F2 -> "xterm" -> Enter -> env | grep SSH
  
- via Super Key -> the environment is correct
+ The returned values should match the results got from the xterm instance
+ that has been ran from unity dash application lens (the one opened with
+ Super).
  
- via Alt-F2 -> it is not
+ The same should be checked for the variable XDG_MENU_PREFIX
  
+ Before this fix happened we had this result:
+   via Super Key -> the environment is correct
+   via Alt-F2 -> it is not
  
- I believe Alt+F2 code path should call into upstart dbus api to "list-env" and import that environment before executing the search result.
