Problem with GtkFileChooserDialog select_folder action

[John Stebbins <stebbins jetheaddev com>]

The problem occurs when I create a GtkFileChooserDialog with action 
GTK_FILE_CHOOSER_ACTION_SELECT_FOLDER and then set the default folder 
with gtk_file_chooser_set_filename or gtk_file_chooser_select_filename.  
Attempting to click "Ok" gives the message "The folder could not be 
created. Error creating directory: File exists".  Simply selecting a 
different file, then re-selecting the default and clicking "Ok" works 
fine.  I've attached a sample program that demonstrates the problem.  Am 
I doing something wrong, or is this a bug?  If it's a bug, is there a 
known work-around?  I've tried various permutations of things and can't 
find a way around it.
