This should use dbusmenu_menuitem_take_children and then run
g_object_unref() on them.  Since child_delete() is going to free the
memory for the GList structure currently pointed to by children, next
isn't necessarily there (in all practical cases it is).  Other solution
is that you could keep next on the stack, but I think take_children() is
probably cleaner.
