What steps will reproduce the problem?

vv.plot([0,1,1,1],[0,0,1,1],[0,0,0,1])

however, no error for

vv.plot([0,1,1,1.0],[0,0,1,1.0],[0,0,0,1.0])

Traceback (most recent call last):
  File "<console>", line 1, in <module>
  File "c:\python33\lib\site-packages\visvis\functions\plot.py", line 150, in plot
    l = vv.Line(axes, pp)

and subsequently, as a result, upon every redraw:

Could you please try with the latest version from the repo? I cannot reproduce 
it and I think we changed something in the handleInvalidValues function.
