FileChooserDialog was added in GTK+ 2.4, and is wrapped in gtkmm 2.4.

I guess that someone created the .glade file on a system that has GTK+
2.4, with glade 2.6, which uses GTK+ 2.4. I don't believe that the the
system (or environemnt) with glade-2.6 is the system on which you are
running this, though I could be wrong.

So, in summary, you are using old versions of GTK+ and gtkmm.
