I agree with that.

Apparently, this does not work with Gtk::FileSelection, which does not
recognize a path unless given the filename in the OS way. The doc says
something of this kind (but only about encodings). See

http://ruby-gnome2.sourceforge.jp/hiki.cgi?Gtk%3A%3AFileSelection

which says :

filename=(filename)
    Sets a default path for the file requestor. If filename includes a
directory path, then the requestor will open with that path as its
current working directory. The encoding of filename is the on-disk
encoding, which may not be UTF-8. See GLib.filename_from_utf8.

I think I will just use the ordinary File.join, then gsub('/', '\')
before giving the name to FileSelection.
