compact test case for weird filechooser behaviour

[Bartosz Kostrzewa <zoombat runbox com>]

A couple of days ago i reported that the filechooserwidget behaves
rather unpredictably when in a GNOME session. Here's a little testcase
that reproduces the behaviour as in gimmage.

compile and launch "./testfilechooser *" in a directory with a couple of
files

-click apply a couple of times to trigger set_filename(), note the
output and what happens in the window, note that get_filename() does NOT
return anything!

-click remove to hide the filechooser widget from the window
-click remove again to make it reappear
-click apply a couple of times and note that the what happens in the
window does not match what is sent to set_filename(), get_filename()
still does not return anything

again, the weird behaviour happens only in a gnome session, but
get_filename() returns an empty string even in a non-gnome session

I use: gentoo ~x86
GTK 2.10.13, GLib 2.12.12, gtkmm 2.10.9, libgnome 2.18.0
