Similar problem happened to me. I would say that I connected to the hidden network once, even if I don't remember if that was when using jaunty or after upgrade to karmic.
What I'm totally sure is that I've attempted to connect to a hidden network (with no password needed) and the network-manager-applet fails to connect to that network.
The network exists and works fine. Using the same machine (dual boot macbookpro 5.5) with Snow Leopard OS, or with nokia symbian v60 I can connect to that hidden network with no problem.
