Gtk::FileChooserDialog + FileFilters

[Paul Davis <pjdavis engineering uiowa edu>]

I'm having a bit of a problem trying to get FileFilters to work with the 
FilerChooserDialog.

I've created both the dialog and the filter. And set it via 
chooser.set_filter( filter ).  The problem is that the files aren't 
filtered.  I've managed to use the chooser.add_filter( filter ) which 
works in adding it to the user-selectable list of filters.  Then at run 
time its possible to select the filter, and the list of files is 
filtered appropriately.  This is mostly an anal retentive its not 
exactly right type of problem, but I was just wondering if anyone else 
had seen something like this.  Or if I completely missed any reference 
to such a thing searching through the list archives.

Things I should probably mention:
Not really sure about where to get the versions, so I'm listing whats in 
the pkg-config files for each package.
gtkmm-2.4    2.6.2
gtk+-2.0        2.6.7

My non anal-retentive satisfying code:

<snip>
   Gtk::FileChooserDialog chooser( "Open Experiment File", 
Gtk::FILE_CHOOSER_ACTION_OPEN ) ;
   chooser.set_transient_for( *this ) ;

   chooser.add_button( Gtk::Stock::CANCEL, Gtk::RESPONSE_CANCEL ) ;
   chooser.add_button( Gtk::Stock::OPEN, Gtk::RESPONSE_OK ) ;

   Gtk::FileFilter filter ;
   filter.set_name( "XML Files" ) ;
   filter.add_mime_type( "text/xml" ) ;

   //This just adds the filter to the list.  There's no initial setting 
of the filter.
   //chooser.add_filter( filter ) ;

   chooser.set_filter( filter ) ;

   string defaultLoc = "/usr/local/data/E1001" ;

   chooser.set_filename( defaultLoc ) ;

   int result = chooser.run() ;
</snip>

Sorry to bother anyone if I'm just completely missing an old bug or 
something.
