When you enter a directory and use F2 to rename a file, and that directory
is updating some files, the focus will change. This is very irritating
because I have experienced several times that I have been renaming a file
and using the delete button to erase some characters - when focus changes,
I accidently delete the file.

How to reproduce:
1. Go into a directory which takes a while to load (in my case, a directory
with a lot of .ogg files)
2. Pick a file, and start renaming it.
3. Because not all files are finished updated, everytime a new file is
updated the focus will go out of the renaming entry.

Note, by "updating" I mean when Nautilus refreshes the view with some new
information, e.g. setting the correct icon after it figures out the file
type, or when a new file is moved into that folder.
