They look different and have different capabilities. FileSelection is
deprecated.

It would probably be best to create a simple-as-possible test case. Then
you could try getting the same error without OpenGL, or try it with a
GtkFileChooser with C instead of a Gtk::FileChooser. I suspect that
gtkmm has not influence on the problem, so it might be in GTK+ or
gtkglex.

valgrind or gdb's backtrace might also help.
