Comment 1 for bug 490200

I can confirm this bug. Most attempts at creating an Ad-Hoc connection result in constant connect/disconnects. A couple times I have managed to get it to stay connected temporarily but at some point everything goes haywire and then I start seeing networks appearing in the list with garbled names that do not exist. Any attempts to modify the network cause the network-manager icon to disappear. Restarting X will get the icon back but does not solve the reconnecting issue or get rid of the strange networks from the list. Restarting the networking service doesn't help either. The only way I have managed to recover from this is to remove the networks from the Network Connections Program in System > Preferences and then reboot.
