I am affected also. Toshiba Portege r835-p56x Ubuntu 12.04 upgraded from 11.10 network-manager 0.9.4.0-0ubuntu4.1 network-manager-gnome 0.9.4.1-0ubuntu2
sudo killall NetworkManager does not fix. System restart fixes the problem. Also, my wired connection is retained when bug is activated. But I am unable to disconnect or reconnect to ANY other networks. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/1011073 Title: network manager submenus empty Status in “network-manager” package in Ubuntu: Confirmed Bug description: Submenus in Network Manager are sometimes unusable as they are not populated. This happens both with the list of available networks and with the VPN list. When the bug happens, it occurs for *both* the wireless submenu and the VPN menu. I know there are entries for those submenus as I can see them with other network UI mechanisms. The issue is intermittent. Expected: Dropping down the menu then hovering over the submenu trigger-point (example: "More networks") shows the additional expected entries (example: more wifi networks to choose from). Actual: Dropping down the menu and hovering over the submenu trigger displays a submenu but the submenu has nothing in it and is unusable.
