Traits ListEditor popup menus broken

[corranwebster]

When running a simple example of a list editor, clicking on the popup menu button causes an error as follows:

File "/Users/cwebster/src/ets/traitsui/traitsui/qt4/list_editor.py", line 280, in popup_menu
    proxy    = sender.proxy
AttributeError: 'NoneType' object has no attribute 'proxy'

Example code which tweaks this:

class SchoolClass(HasTraits):
    # List of the students in the class
    students = List(Str)

    view = View('
             Group(
                  Item('students', 
                       style='custom',
                       editor=ListEditor(rows=5),
                       show_label=False,
                  ),
                  show_border=True,
                  label='Students'
            ),      
            title = 'Class',
            width=300,
            height=200,
            resizable=True
        )
