I can reproduce this on clean installations of Ubuntu 10.04 & 12.04 with the following
procedures (slight changes due to package name changes etc)

Not enough information was provided for us to be able

http://bugs.php.net/how-to-report.php
If you can provide more information, feel free to add it
to this bug and change the status back to "Open".
Thank you for your interest in PHP.
I can't reproduce this with the current version in git on 5.3 or 5.4
Can you try a newer compile of php-gtk? Also what gtk library version are you using, and are you
using Ubuntu distro builds of php - if so please try with a stock build of PHP

Description:
------------
The first time the OK button on the dialog is clicked the custom signal is emitted correctly, on the
second click php segfaults on the call to emit().
If no object is provided to emit() the second signal emits without segfault as expected.
Test script:
---------------
<?php
/** Class implements custom signal 'product-ready'. */
class customDialog extends GtkDialog {
public $__gsignals = array(
'product-ready' => array(
GObject::SIGNAL_RUN_LAST,
GObject::TYPE_BOOLEAN,
array(
GObject::TYPE_PHP_VALUE
)
)
);
public function __construct($title, GtkWindow $parent) {
parent::__construct($title, $parent, Gtk::DIALOG_MODAL);
$product = new stdClass();
$okButton = new GtkButton('OK');
$this->action_area->add($okButton);
$okButton->connect_simple('clicked', array($this, 'ok_clicked'),
$product);
}
public function ok_clicked(stdClass $product) {
$this->emit('product-ready', $product);
}
}
GObject::register_type('customDialog');
$window = new GtkWindow();
$window->show_all();
$dialog = new customDialog('fire signal dialog', $window);
$dialog->show_all();
$dialog->connect('product-ready', 'product_ready');
function product_ready() {
echo 'segfaults on second signal' . "\n";
return true;
}
Gtk::main();
