Network Manager applet shows "More networks" entry with no sub-menu

[ooze]

In a network environment with many detected wireless networks (iwlist wlan1 scanning shows 18 networks), the Network Manager applet shows 5 networks and a "More networks" entry. However, when this entry is selected there is no sub-menu.

Best I can do for now is to mark this confirmed, let's try to figure out in which cases this works. Maybe there has to be exactly five networks available from the interface's scan results (plus the active network, so six?).

Here is works just fine; if I connect a second device I see a submenu in More Networks for both devices.

When the "More networks" menu is empty, the "VPN Connections" menu is also empty.

I sometimes have a similar problem. Both the "More networks" submenu and the VPN submenu are there, and they have their expansion arrows, but the submenus show up as empty, with just a thin rectangle sticking out, not even the full width you'd expect. I've attached a couple of screenshots. Could this qualify as a different bug?

Not sure what triggers it. It wasn't happening in Maverick. I did a fresh install, not an upgrade. I'm running amd64 Natty on a Thinkpad W510 with the Intel Centrino Ultimate N 6300 card, and full disk encryption, installed using the alternate installer on USB. I'm using Ubuntu-Classic interface (metacity), the ambience theme, Human controls, and Humanity icons.

I rarely reboot, almost always suspending and resuming instead. I think when this problem does show up, it might be after a resume. I don't think I've ever seen it happen after a reboot. Also, I'm running the Maverick kernel due to power consumption issues with the Natty kernel. I haven't tried running the Natty kernel extensively with a lot of suspend and resumes

Same issue in Ubuntu 12.04

I think the duplicate status is wrong:
 - when "VPN Connections" and "More Networks" menus are empty, the Network Manager icon itself is perfectly clickable and reacts as expected;
 - there is an easy workaround for bug #779754: restarting network-manager service. That workaround doesn't fix this issue when it happens. The only way I've found so far is to reboot.

After some poking around and reading the other bug comments, I take it back - it well may be a duplicate of what is discussed in bug #779754.

I am sorry for disturbance here.
