I have a similar problem, every thing was working will with me but yesterday i tried to use an application "xnetcardconfig" to configure my network, today when i turned on my computer i found the network icon with that x on it, and the same error message which pedro had "Error displaying connection information:No valid active connections found!" The difference is with gnome-nettool, in my case the connection is not correct it shows : loopback interface (lo) I tried to reinstall network-manager-gnome and network-manager, but that didn't help.
