If you ask Nautilus to view a text file you get a (very long) pause then
the text file is displayed. The left hand area where you get "view with"
buttons shows only a narrow bar of button top/button bottom but with no
actual options in it.
I'm not sure I understand exactly what you mean, but I did the following:
- log on
- type /etc/X11/XF86Config into Nautilus location bar
- XF86Config is displayed and I have "Open with gedit" and
"Open with..." buttons in the sidebar
So I think it works for me...
Reopen if we figure out how to reproduce
