If no label is given then it assumes that you are wanting to use a stock 
label and so it calls wxGetStockLabel to look it up, which is basically 
just a big switch statement that maps IDs to strings.  If the given ID 
is not in there then it does the assert.  These work for me:

  >>> import wx
  >>> menu = wx.Menu()
  >>> mi = wx.MenuItem(menu, wx.ID_EXIT)
  >>> mi = wx.MenuItem(menu, -1, "Hello")
  >>> mi = wx.MenuItem(menu, wx.ID_EXIT, "Goodbye")
  >>> mi = wx.MenuItem(menu, wx.NewId(), "Foo")

These will fail:

  >>> mi = wx.MenuItem(menu, wx.ID_DEFAULT)
  >>> mi = wx.MenuItem(menu, -1)
  >>> mi = wx.MenuItem(menu, wx.NewId())

IIRC, on Linux it is also checking with GTK for stock icons and labels 
rather than just the built-in set so maybe there is some different 
assumptions made...
