I found a similar problem in ubuntuforums.org.

There, the solution apparently is:

sudo apt-get install sysv-rc-conf sudo sysv-rc-conf 

A window will show. Arrow down near the end to "wicd". Use the spacebar to put an X in 2, 3, 4, & 5. Enter q to quit. Reboot.

Edit:

Try this:

edit config file from terminal console:

gedit /etc/wicd/manager-settings.conf 

search for:

sudo_app = 0 

change to:

sudo_app = 1
