Thanks Bruce, I'll check this out. I'm worried that something like
this may not work as the action my extension performs is similar to
swapping a symlink for the current directory. So, you type A in your
nautilus bar, which maps to B, so you see the contents of B. You click
a button and the extension now maps A to C, so refreshing B won't
help. Nautilus needs to know to refresh to "base" location in the
location bar. So I think this is why pressing F5 works just fine, but
touching files, adding files et cetera, doesn't help because nautilus
is looking in B and not C. There doesn't seem to be anything I can do
in B or C that will make it refresh the contents based on A. Does this
make sense?

Is there a way to mark "A" as dirty and needing to be refreshed?
