ListItems.insert() throws exception

Attempting to insert a ListItem into a ListItems object throws an exception. Other list operations also throw exceptions - like pop() - while others appear to work as expected - like append().

Here's the code:

myListItems = mc.ListItems()
myListItems.insert(0, mc.ListItem(mc.ListItem.MEDIA_VIDEO_EPISODE))
print '>>> DONE <<<'

Here's the error:
