Description:
------------
Bug in drag'n'drop:
Drag from "from" button to "to" button.
You will get a segfault.


Reproduce code:
---------------
<?php
$wnd = new GtkWindow();
$wnd->connect_simple('destroy', array('Gtk', 'main_quit'));
$hbox = new GtkHBox();
$wnd->add($hbox);

$btnFrom = new GtkButton('From');
$btnTo   = new GtkButton('To');

$hbox->pack_start($btnFrom);
$hbox->pack_start($btnTo);

$btnFrom->drag_source_set(
    Gdk::BUTTON1_MASK,
    //change to text/plain, and it works
    array(array('text/xml', 0, 1)),
    Gdk::ACTION_COPY | Gdk::ACTION_MOVE
);
$btnFrom->connect('drag-data-get', 'onGetDragData');


$btnTo->drag_dest_set(
    Gtk::DEST_DEFAULT_ALL,
    //change to text/plain, and it works
    array(array('text/xml', 0, 1)),
    Gdk::ACTION_COPY | Gdk::ACTION_MOVE
);

function onGetDragData($widget, $context, $selection, $info, $time) {
    var_dump($selection);
}


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

I fixed this in CVS. Now the selection, target, and type properties of GtkSelectionData are GdkAtom objects and you have to cast them to (string) in order to get the string representation. Let me know if this is going to be too cumbersome. I may adjust GtkSelectionData to have just strings instead of GdkAtom objects for properties.

Also, when running your example the 'data' property is NULL. Is that normal?

The survey basically wants to know what customers think of their products and how happy clients are with their general customer services.

So, if you have shopped at the Home Depot store or are a regular shopper, you should consider leaving some feedback.
