Comment 4 for bug 212789

I too suffer from same issue, tried using Nick Frolov's advice on manually unmounting the .gvfs folder.
The problem is only half solved...
 ls -la |grep .gvfs
dr-x------ 2 user user 0 2008-04-19 18:35 .gvfs

Notice the permissions on folder?
on my 64bit systemm the folder has also write permission.

At the current state, nautilus seems sluggish and it crashes from time to time?
