Home folder doesn't correctly open in panel

[palimmo]

When I open Home folder from the Launcher, Nautilus opens and it is completely maximized.
But the panel reports commands of the previous application I was using, for example Firefox. As you can see in the two images.
In the second image is visible that the triangle at the left of the Home Folder is blue, instead of white.

If I choose one of the voice of the panel, it is one of the Firefox voices. For example, if I try to close the window clicking on X, it asks me to close the Firefox window instead of the Nautilus one.
If I click somewhere in the nautilus window, the panel changes and reports correctly the Nautilus commands.

If I'm working on a Firefox maximized window and then I click on the launcher-> Home folder, I can reproduce this bug always.
And unfortunately this happens really often...

I'll subscribe it.
Thanks.
