Yes, same thing here. I recently coded a bit with VTK outside of Mayavi
and it's crazy how the thing likes to segfault. Each time it segault it's
because the user did something not right according to its rules, but it
doesn't pardon anything. Unfortunately this behavior leaks a bit through
Mayavi.

You were almost there. If I change a bit the last lines of your script to
the following it works (don't know why I have to specify the vmin and
vmax explicitely):
figure = mlab.figure(1, size=(500, 500))
mlab.clf()
voltage = np.linspace(-90, 60, num=20)
surf = mlab.pipeline.surface(combination, vmin=voltage.min(),
vmax=voltage.max())
# Scalars
combination.point_data.scalars = np.repeat(voltage, 24) # 24 points per
cylinder
combination.point_data.scalars.name = 'Voltage'
# Selector and Picker
cyl_sel = CylSelector()
cyl_sel.picker = figure.on_mouse_pick(cyl_sel.picker_callback,
type='cell')
mlab.scalarbar(surf)
