Yes: you were starting the 'plain' ipython, and for interactive usage of TVTK/M2, you need to handle the WX threading issues correctly. IPython will do this, but you need to start it as ipython -wthread from the terminal (or an alias/shortcut) so that it configures itself explicitly for WX threading (used by Mayavi2). I'll add a note to the manual indicating that this kind of usage is probably not a good idea. I personally don't use it like that, and simply start ipython manually (optionally with threading support when I need it).
