Description:
------------
Im using php-gtk2 from cvs.
when im trying to get an Hebrew letters from GtkEntry and put int in other GtkEntry i get a Segmentation fault.
i think its a pango related maybe?

Reproduce code:
---------------
#!/usr/bin/php-gtk
<?php
function delete_event()
{
    return false;
}

function shutdown()
{
    print("Shutting down...\n");
    gtk::main_quit();
}

function hello()
{
    global $window;
    print "Hello World!\n";
    $window->destroy();
}
/*
$window = new GtkWindow();
$window->connect('destroy', 'shutdown');
$window->connect('delete-event', 'delete_event');
$window->set_border_width(10);

$button = new GtkButton(phpversion());
$button->connect('clicked', 'hello');
$window->add($button);
*/
function on_button1_clicked()
{
global $php,$zend;
$php->set_text($zend->get_text());
//gtk::main_quit();
}
$glade = new GladeXML( dirname( __FILE__) . "/xml.glade");
$glade->signal_connect("shutdown","shutdown");
$glade->signal_connect("on_button1_clicked","on_button1_clicked");
$php = $glade->get_widget("php");
$php->set_text(phpversion());
$zend = $glade->get_widget("zend");
$zend->set_text(zend_version());
//$window->show_all();

gtk::main();
?>

1) Where is the Hebrew text? This script doesn't have any.. and the Zend and PHP versions are hard-coded in English.. I need to be able to reproduce what you're seeing before I can fix anything.
2) What is your codepage setting (in your php.ini)?
3) Shorter scripts are very much welcomed.  Example:

<?php

function shutdown() {
    print("Shutting down...\n");
    gtk::main_quit();
}

function on_button1_clicked($php, $zend) {
    $php->set_text($zend->get_text());
}

$glade = new GladeXML( dirname( __FILE__) . "/xml.glade");
$glade->signal_autoconnect();

$php = $glade->get_widget("php");
$php->set_text(phpversion());
$zend = $glade->get_widget("zend");
$zend->set_text(zend_version());

gtk::main();

?>

OK, I spent some time now doing battle with my (UK) setup and the contents of an old email with a Hebrew date on it:

<?php

function shutdown()
{
    print("Shutting down...\n");
    gtk::main_quit();
}

function on_button1_clicked()
{
global $php, $zend;

$php->set_text($zend->get_text());
}

$glade = new GladeXML( dirname( __FILE__) . "/xml.glade");
$glade->signal_autoconnect();

$php = $glade->get_widget("php");
$php->set_text("??? ????? 18 ???????");
$zend = $glade->get_widget("zend");
$zend->set_text("??? ????? 10 ???????");

gtk::main();

?>

(forgive the Unicode - assuming that's what it comes out as after I press submit - on my laptop and in my codepage setting it's ISO-8859-8)

All I can think is that a) you've skipped the codepage setting or b) you didn't install Pango's runtime Hebrew support, because it works perfectly here.  I'm therefore closing this report.

Remembering to change the status might've been a smart move on my part :)
