[Lucazade]

When opening nautilus there are two buttons on the panel taskbar.
one is correct, the other disappear after 10 sec and it is called "opening home folder".

this happens only with nautilus.

I can confirm this bug under the same configuration. For instance, when opening my "Downloads" folder, the "Opening Downloads" button appears first. Then, after a few seconds, a new button appears to the left of this one. The original, "Opening..." button disappears after few more than 10 seconds and no menu appears when right-clicking it.

I can confirm this too. And this only happens if I open a directory from a menu on the panel for example typicaly from the Places menu. If I open a directory in a new Nautilus window from the desktop or from an other Nautilus window there isnt a second button on the panel.
