Description:
------------
When dragging 3x from the window to itself, php crashes. You need to apply the GtkSelectionData get_uris/set_uris patch I sent to php-gtk-dev today first.

Reproduce code:
---------------
<?php
$wnd = new GtkWindow();
$wnd->connect_simple('destroy', array('Gtk', 'main_quit'));
$wnd->drag_source_set(Gdk::BUTTON1_MASK, array(), Gdk::ACTION_COPY);


$wnd->drag_source_set(
    Gdk::BUTTON1_MASK,
    array(array('text/uri-list', 0, 0)),
    Gdk::ACTION_COPY
);
$wnd->drag_dest_set(
    Gtk::DEST_DEFAULT_ALL,
    array(array('text/uri-list', 0, 0)),
    Gdk::ACTION_COPY
);
$wnd->drag_dest_add_uri_targets();

$wnd->connect('drag-data-get', 'onGetDragData');
$wnd->connect('drag-data-received', 'onDragDataReceived');


function onDragDataReceived($widget, $context, $x, $y, $data, $info, $time) {
    echo "drag-data-received\r\n";
    var_dump($data->get_uris());
}
function onGetDragData($widget, $context, $selection, $info, $time) {
    echo "drag-data-get\r\n";
//    $selection->set(Gdk::atom_intern('text/variable'), 8, 'abc', 3);
    $selection->set_uris(array('file:///', 'file:///home/cweiske/a.out'));
}


$wnd->show_all();
Gtk::main();
?>

Actual result:
--------------
*** glibc detected *** corrupted double-linked list: 0x08dd5e00 ***

Program received signal SIGABRT, Aborted.
