This is not a duplicate of bug #436324. There's a similar signature, but has a new root cause as indicated by the sudden increase in duplicates in precise.

This was fixed with a rewrite of the wireless bits for menuitems in the indicator:

network-manager-applet (0.9.2.0+git.20120126t000800.5151959-0ubuntu3) precise; urgency=low

  * debian/patches/lp829673_gconf_hide_applet.patch: allow toggling the applet
    visibility. (LP: #829673)
  * debian/patches/nm-applet-use-indicator.patch: completely replace the old
    wireless menu item creation code overriding NMNetworkMenuItem objects to
    rewrite it more simply with GtkImageMenuItems. This should really take care
    of the memory leaks. (LP: #930491)
