I booted into Forensics Mode, then tried to run the Wicd Network Manager, but nothing came up. I then looked at its menu option's properties and saw that it executes "wicd-client --no-tray", so I put that into a terminal. Here is its output:

root@bt:~# wicd-client --no-tray

Feel free to ask me to try something to debug it, though it should be easy to reproduce...
