CurveTable does not check list is valid crashes.

[GoogleCodeExporter]

What steps will reproduce the problem?

Try to create a CurveTable with a index bigger than the size

e.g.

tab=CurveTable([(0,0),(2048,.5),(4096,.2),(6144,.5),(8192,0)], 0, 20,1024)

What is the expected output?

Error message should be produced.

 What do you see instead?
