Nautilus weird behaviour

[Gabriele Monti <psicus78 gmail com>]

Hi,
I'm just posting a strange behaviour of Nautilus that I discovered a few 
days ago, don't know if it is a bug or a wanted feature so I'm just 
posting a mail in this list.

This is the case:

Using nautilus spatial ("always open on browser windows" unchecked), I 
have a browser window opened, displaying directory, let's say "/". I 
(single) click on the small triangle to unfold directory "/usr". Then I 
(single) click again on the triangle to unfold "/usr/lib" and again 
unfold "/usr/lib/dbus1-0". Now let's say I select the subfolder 
"/usr/lib/dbus1-0/include", once it is selected it cannot be unfolded. 
If I select any other folder in the window and then click on "include" 
small triangle to unfold it I'm able to do it. Is this a wanted behaviour?

p.s. I just discover that "include" can be unfolded by clicking outside 
of the triangle, on the left side, really close to the top left corner, 
even more weird!

p.s2. it looks like if you use nautilus "spatial" this problem comes one 
level higher than with standard browsing mode.

thanks!
