Don't know if it might help, I had problems with network-manager as well, and each time network-manager crashed, I had to type "killall gnome-panel" in a terminal in order for the applet to restart. Then I added to my sessions file ("System" > "Preferences" > "Start Applications") the command "nm-applet --sm-disable" and the problems went away.
