Title:
  nm-applet icon not showing when /proc is mounted with hidepid!=0

Status in Network Manager Applet:
  New
Status in network-manager-applet package in Ubuntu:
  Confirmed

Bug description:
  Steps to reproduce:

  1. (Re-)mount /proc with hidepid=1 (or =2)
  2. Restart nm-applet

  nm-applet's icon does not reappear after the restart. This used to
  work with version 1.0.

  
  Original bug description:

  Since I upgraded to -proposed network-manager and network-manager-gnome versions, nm-applet no longer works.
  Manually starting it on a console give:

  $ nm-applet

  (nm-applet:6250): nm-applet-WARNING **: GDBus.Error:org.freedesktop.NetworkManager.AgentManager.PermissionDenied: Unable to determine request sender and UID.
  (nm-applet:6250): libnm-CRITICAL **: nm_client_get_nm_running: assertion 'NM_IS_CLIENT (client)' failed

  (nm-applet:6250): libnm-CRITICAL **: nm_client_get_devices: assertion 'NM_IS_CLIENT (client)' failed

  What's odd is the NM and NM-gnome base versions are not identical:
