As is noticed in the bug you refer to, it all depends on which version 
of gtk+ you use. Which version do you use?

I tested with a modified version of the example program
http://git.gnome.org/browse/gtkmm-documentation/tree/examples/book/buttons/filechooserbutton
and gtk+-3.0 versions 3.4.2 and 3.7.7 (3.7.7 downloaded from the git 
repository 2013-01-20), Ubuntu 12.04.

In both cases the results are

1. Go to a folder by a number of double clicks, don't select a folder, 
click Open:
  both get_filename() and get_current_folder() return the folder I've 
gone to.

2. Go to a folder by a number of double clicks, select a folder by 
single-clicking it, click Open:
  get_filename() returns the selected folder,
  get_current_folder() returns the folder I've gone to, i.e. the folder 
above the selected one (an empty string, if the number of double-clicks 
is zero).

This behaviour seems quite reasonable. The description of get_filename() 
says "If the file chooser is in folder mode, this function returns the 
selected folder."

But I suppose the "API 2.4" in the subject line means that you use gtkmm 
2 and gtk+ 2.
