Description:
------------
Cannot get GtkFileSelection->complete to work, using current release.

Took online Manual example of object construction, and added a complete stmt.  Results invalid.



Reproduce code:
---------------
<?php
//Creating and initialising the file selection prompt
$filePrompt = new GtkFileSelection('GtkFileSelection Demo');
$filePrompt->connect_simple(
    'destroy',
    array('Gtk', 'main_quit')
);

$filePrompt->complete("*.txt");

 
//Adding a quit button that destroys the prompt
$filePrompt->cancel_button->set_label('Quit');
$filePrompt->cancel_button->connect_simple(
    'clicked',
    array($filePrompt, 'destroy')
);
 
//Add an OK button that displays the file selected on click
$filePrompt->ok_button->set_label('Show the file');
$filePrompt->ok_button->connect('clicked', 'showFile');
 
//Callback function that displays the file name
function showFile($okbutton)
{
    $filePrompt = $okbutton->get_toplevel();
    $fileName = $filePrompt->get_filename();
    $message = new GtkMessageDialog(
        null,
        0,
        Gtk::MESSAGE_INFO,
        Gtk::BUTTONS_OK,
        'You selected: ' . $fileName
    );
    $message->run();
    $message->destroy();
}
 
//Show the prompt and start the main loop
$filePrompt->show();
Gtk::main();
?>

Expected result:
----------------
You should see only txt extension files in results window.  

Actual result:
--------------
You get all files listed
