OverFlowError in Point.py

[Ortbauer Martin Leopold]

This error made my plot unuseable:

Traceback (most recent call last):
  File "/usr/lib/python2.7/site-packages/pyqtgraph/graphicsItems/PlotCurveItem.py", line 157, in boundingRect
    py = 0 if py is None else py.length()
  File "/usr/lib/python2.7/site-packages/pyqtgraph/Point.py", line 102, in length
    return (self[0]**2 + self[1]**2) ** 0.5
OverflowError: (34, 'Numerical result out of range')

I don't really know what this part of the code is doing, but a simple try, except clause and returning 0 fixed it for me, my patch:

Thank you! This will be fixed in the next release.
