Ubuntu Gnome + AppKeys bookmarked shortcut problem "fix"
On Ubuntu Gnome 15.04 if chrome is bookmarked + AppKeys extensions. Instead of focusing the opened chrome browser it opens new instance.
For the moment "a solution" is to delete the current "/usr/share/applications/google-chrome.desktop" shortcut file. Because it replaces the changes in it. Create a new file "/usr/share/applications/google-chrome-c.desktop" i put "-c" not to be replaced automatically.
