Files lens and xdg-open only open nautilus but not the correct applicatiion
In 12.04, since yesterday the behavior of the dash in Unity has changed.
Previously (and I assume it is the default choice), when selecting a file in the dash, the file was automatically opened with its corresponding application. Now, the folder containing the file is opened in Nautilus instead.
(I have to mention that I have installed XFCE)
How do I revert to the first behaviour ?
