unity launcher showing two instances of open applications

[aveem ashfaq]

If you look at the screenshot posted as an attachment, you will find that there are two instances of nautilus and two instances of terminal displayed on the left bar. One of the instances is the stock icon which I have locked to the launcher. The other icon is the running instance. It is showing that nautilus and terminal is open. This is a bug with development version of yaketty yak on 29th september latest build. I have all packages upgraded.
