OK, I will bring this up once again as I've tried to reproduce this bug.
Clean install of dapper. Updated fully. Installed package network-manager-gnome. Ran the command "sudo gtk-update-icon-cache -f /usr/share/icons/hicolor" just to be sure nm-applet --sm-disable starts. Edited /etc/network/interfaces to comment out everything but "auto lo" and "iface lo inet loopback". Restarted machine. nm-applet started fine, when I clicked it it showed both available networks. I clicked the free one, the one I use (with webpage https authentication after which I can surf freely). After about 30 seconds nm-applet stopped spinning its icon and showed the "no connection" icon again and indeed, it did not work, so we have some kind of progress, it does not assign a bogus IP anymore. It's all zeros. I will attach my targzipped syslog in a few moments. I know the wlan0 connection looks very ugly there, but it works fine in reality (without using network-manager-gnome).
