Public bug reported:

broken out of bug 780602, because we believe the root cause to be
different. From that bug report:


I experience exactly the same symptoms as the bug report description
has.

After some time nm-applet stops reacting to user input and submenu
entries do not populate. This is with latest 12.10 packages.

I noticed that the indicator tries to get the menu but it fails - dbus-monitor 
output below:
method call sender=:1.12 -> dest=:1.67 serial=14296 
path=/com/canonical/Unity/Panel/Service; 
interface=com.canonical.Unity.Panel.Service; member=ShowEntry
   string "0x26ef470"
   uint32 0
   int32 1147
   int32 24
   uint32 1
   uint32 1356027813
method return sender=:1.67 -> dest=:1.12 reply_serial=14296
method call sender=:1.67 -> dest=:1.14 serial=107621 
path=/org/ayatana/NotificationItem/nm_applet/Menu; 
interface=com.canonical.dbusmenu; member=AboutToShowGroup
   array [
      int32 80799
   ]
error sender=:1.14 -> dest=:1.67 
error_name=org.gtk.GDBus.UnmappedGError.Quark._LIBDBUSMENU_2dGLIB.Code0 
reply_serial=107621
   string "The IDs supplied '[80799]' do not refer to any menu items we have"

When some item is clicked (e.g. disconnect for current wifi AP) the following 
happens:
signal sender=:1.67 -> dest=(null destination) serial=107704 
path=/com/canonical/Unity/Panel/Service; 
interface=com.canonical.Unity.Panel.Service; member=EntryActivated
   string ""
   struct {
      int32 0
      int32 0
      uint32 0
      uint32 0
   }
method call sender=:1.67 -> dest=:1.14 serial=107705 
path=/org/ayatana/NotificationItem/nm_applet/Menu; 
interface=com.canonical.dbusmenu; member=EventGroup
   array [
      struct {
         int32 80846
         string "clicked"
         variant int32 0
         uint32 106251172
      }
   ]
error sender=:1.14 -> dest=:1.67 
error_name=org.gtk.GDBus.UnmappedGError.Quark._LIBDBUSMENU_2dGLIB.Code0 
reply_serial=107705
   string "The IDs supplied '[80846]' do not refer to any menu items we have"

So this looks like like dbus menu is losing the IDs or nm-applet is
using the ids that are no longer valid.
