Open minimized nautilus window and not open home in launcher

Solution 1:

This has been confirmed to be a bug on nautilus. You may add yourself to this bug as it affects you(you will need a launchpad account to do this).

The easiest workaround for this is to hover over to the nautilus icon on the launcher using your mouse pointer and scroll using the middle button if you are using a mouse. If not, you can use the touchpad's scrolling feature, i.e., either two-finger scrolling or edge scrolling or whatever you use to scroll using your touchpad.

Note: This feature of bringing an already open window to the front works with all applications on Ubuntu 14.04.
