Whenever I click on my chrome shortcut I get a new window (as expected) but I also get a new Unity entry with a different icon (one from an iconset I had been using before upgrading to 14.04 – don't really remember the name). The new unity entry does not seem to originate from a correct .desktop entry because all the submenus are missing from it (New incognito window, New Window etc.) and it has a permanent tag '(1) Facebook' no matter the window title (see attached picture).
I have uninstalled and reinstalled chrome in hope that it would help which it did until restart but now I get the same behaviour.
Note that I haven't altered any .desktop files regarding chrome and I can only find one file:
which seems to be correct (with submenus etc.)
