Superb, rolling back PPA worked for me !
sudo apt-get remove libgtk-3-common
sudo apt-get install ppa-purge
sudo ppa-purge ppa:gnome3-team/gnome3
sudo apt-get dist-upgrade
sudo apt-get install gnome-panel
Thanks.

The upgrade cannot complete because of your custom PPA from gnome 3. You will
need to remove this PPA, and all other PPA's along with their packages, to
continue. Consider the tool 'ppa-purge'.
