Bug#645975: alacarte: can't disable menu items

[Paul C. Bryan]

Package: alacarte
Version: 0.13.2-3
Severity: important

Under GNOME 3, you can no longer disable (or enable) menu items in Alacarte. Console output:

Traceback (most recent call last):
  File "/usr/share/alacarte/Alacarte/MainWindow.py", line 432, in on_item_tree_show_toggled
    self.editor.setVisible(item, False)
  File "/usr/share/alacarte/Alacarte/MenuEditor.py", line 200, in setVisible
    menu_xml = self.__getXmlMenu(self.__getPath(item), dom, dom)
  File "/usr/share/alacarte/Alacarte/MenuEditor.py", line 473, in __getXmlMenu
    node = self.__addXmlMenuElement(element, name, dom)
  File "/usr/share/alacarte/Alacarte/MenuEditor.py", line 484, in __addXmlMenuElement
    return element.appendChild(node)
  File "/usr/lib/python2.7/xml/dom/minidom.py", line 1550, in appendChild
    "two document elements disallowed")
xml.dom.HierarchyRequestErr: two document elements disallowed

This may be related to bug #645470, as I see similar errors in the console.

My rationale for classifying this as important rather than normal
is because this is very commonly used functionality that has broken.
