[Debian-med-packaging] Bug#800135: This is a bug in the mayavi2 package, or deeper

[Gael Varoquaux]

I can reproduce the problem without mne-python. It's a problem in the
python-vtk package, and maybe even in the libvtk package. The following
code reproduces the problem:

python -c "import vtk; vtk.vtkWindBladeReader()"
