I also report having the same issue. The applet not only becomes completely unresponsive, but the sub-menus do not show up anymore. The VPN Connections sub-menu shows as completely empty and that is how I usually realize it is frozen. I do not know of any way for how to reproduce this issue. The following command restores the use:
(killall nm-applet && nm-applet &)
