Keyboard layout incorrect in unity

Problem: keyboard layout in Unity appears to be BE (azerty) (as shown in the icon in Unity panel top right), but when typing it turns out to be EN (querty). I just have to click on the BE-icon and "choose" BE again for the keyboard layout to be correct. But the problem returns after every reboot.
System: Ubuntu 14.04.1 (fresh install) on a HP Envy dv7 laptop

Solution:

• as found in the comments on bug #1238346: 
• delete the ~/.config/ibus folder with the command:
  rm -rf ~/.config/ibus
• then type ibus-setup and in the window that appears, in the "Advanced" tab, tick "use sytem keyboard layout"
• close all windows and reboot.
