FileChooserDialog with ACTION_SELECT_FOLDER dies

[Vladislav Grinchenko <3rdshift comcast net>]

Hi,

if I run stock FileChooserDialog example from gtkmm source code with 
--g-fatal-warnings, click on "Choose Folder" button and attempt to
create a new folder and then select it, the example dies:

Gtk-CRITICAL **: file gtktreemodelsort.c: line 1275
(gtk_tree_model_sort_real_unref_node): assertion `GTK_TREE_MODEL_SORT
(tree_model)->stamp == iter->stamp' failed aborting...

---------------------------------------------

The dialog lets me create and assign a new folder name, but then it
wouldn't show the name in the file list. When I try to go one directory
up it crashes. The folder is created in the file system.

% pkg-config --modversion gtkmm-2.4
2.4.4

This happens on Fedora Core 2.

Is there a way to disable 'Create Folder' button in the top right corner
of the dialog?

I examined the interface and set_action() take only an enum value (one
of four). The stock example rightfully uses
Gtk::FILE_CHOOSER_ACTION_SELECT_FOLDER in 
on_button_folder_clicked() which accoding to Gtk+ documentation should
disable 'Create Folder' button (if my interpretation is correct):

"Indicates an Open mode for selecting folders. 
 The file chooser will let the user pick an existing folder."

Any hint?

thanks,
-Vlad
