Debian unstable, GTK+ 2.6.2, libgnomevfs2-0 2.8.3-11.

Something seems wrong.  When I run the following program, which opens a file
chooser on my home directory, it hangs for a good 8-10 seconds before the watch
pointer goes away.  For almost all of that time, the GUI is blocked, and moving
windows over top of the dialog shows that it is not responding to expose events.

For comparison, the old file chooser widget loads my home directory instantly. 
My home directory has 262 non-hidden directories and 543 files in it of various
types.  It is not NFS mounted.

int
main (int argc, char **argv)
{
    GtkWidget *chooser;
    gtk_init (&argc, &argv);
    chooser = gtk_file_chooser_dialog_new ("...slow...",
                  GTK_WINDOW (window), GTK_FILE_CHOOSER_ACTION_OPEN,
                  GTK_STOCK_CANCEL, GTK_RESPONSE_CANCEL, GTK_STOCK_OK,
                  GTK_RESPONSE_OK, NULL);
    gtk_file_chooser_set_current_folder (GTK_FILE_CHOOSER (chooser),
                                         getenv ("HOME"));
    gtk_dialog_run (GTK_DIALOG (chooser));
    gtk_widget_destroy (chooser);
    return 0;
}
