I think I'm experiencing the same issue. After running overnight, the NM applet becomes unresponsive--clicking on any menu item does nothing, and the submenus are empty. I tried restarting the network-manager service once but it did not fix the problem--I had to also kill and restart nm-applet. I'm using 11.04 amd64 on a brand-new System76 Serval Professional.

Interestingly, this bug doesn't happen on any of my other computers, all of which are also running 11.04 amd64. This computer is also the only computer I have with 802.11n support (Centrino Advanced-N 6230 rev 34), which I am using with a Netgear WNDR3700v2 router. Looking at Jamin's NetDevice.wlan0.txt file, he has 802.11n support too.

Perhaps this is a bug in NetworkManager's 802.11n support or in a 802.11n driver?
