Comment 8 for bug 802964

What's missing as of Alpha 2 is libgnome2-0 (gnome-open
This is what's preventing the opening of the trash folder from the launcher icon

While installing it will resolve this issue, it will break again if a dir. is opened with anything but nautilus.

Doing that creates 2 inode/directory= lines, one the default, the other an added association.
The default one is currently incorrect but that's another bug and not that important here.

What does matter is when opening from unity launcher it will use the first listed .desktop on the inode/directory= line in the Added Associations section which is ALWAYS going to be something other than a valid nautilus .desktop

Another way will be needed to really fix this
