Please describe the problem:
Almost all of our directories are NFS ones mounted by autofs.
Autofs is configured to have a timeout of 60s, which means that the directory is automatically umounted if the system doesn't see open files in it.
This makes nautilus automatically comes back to the home directory after 60s.






Steps to reproduce:
1. Browse a network directory with nautilus
/opt/documentations/alltechnicaldocs (without opening a file)

2. After 60s (autofs setting), it comes back automatically to your home directory



Actual results:


Expected results:
nautilus (gnome-vfs) should keep the folder opened.

Does this happen every time?
yes

Other information:
This makes nautilus unusable in environments where there's a lot of nfs shares.
(users find too much annoying to have nautilus comes back automatically to their home when they are borwsing folder with a lot of files in it)
