Using g_object_get_data() in a NautilusMenuItem callback

[Boyd Timothy <boyd timothy ws>]

Could someone let me know if this is the right way to use  
g_object_get_data() in my callback function in my NautilusMenuItem  
implementation?  Something I'm doing isn't working quite right and it's  
causing Nautilus to crash when I select this item from the context  
menu.

The entire code can be found in this file:  
http://forge.novell.com/modules/xfmod/cvs/cvsbrowse.php/ifolder/ 
nautilus-ifolder/src/nautilus-ifolder.c?rev=1.1&content-type=text/ 
vnd.viewcvs-markup

Here is where I think the problem might begin:

static void
create_ifolder_callback (NautilusMenuItem *item, gpointer user_data)
{
	g_print ("Convert to iFolder selected\n");	
	NautilusFileInfo *file;
	gint error;
	file = NAUTILUS_FILE_INFO (g_object_get_data (G_OBJECT (item),  
"files"));
//	file = (NautilusFileInfo *)user_data;
	if (file == NULL)
		return;

	error = create_local_ifolder (file);
	if (error) {
		/* FIXME: Figure out how to let the user know an error happened */
		g_print ("An error occurred creating an iFolder\n");
	}
}
