Describe the problem:
nurbs Curve Shape node method  .cvs() fails with exception.

What Version of Maya are you using? 2011 x-64

On what operating system? (be as specific as possible and include service
packs, 64bit vs 32bit, etc)
Linux 

What Version of PyMEL are you using? 1.03

What is the expected output? What do you see instead?
a list of CV objects

If possible, provide a few lines of code to reproduce the problem. It helps
us if your code will reproduce the problem from a new scene.

theCurve = pm.curve(d=3, p=[(0, 0, 0), (0, 0, 3), (0, 0, 6), (0, 0, 9)])
theCurveShape =  theCurve.getShape()
theCVs = theCurveShape.cvs(0,2)

Does maya.cmds exhibit the same problem? N/A. this is using an api call.

Please provide any additional information below.

here is the exception it generates:
theCurve.cvs(0,3)

I get the same on Maya 2012, Linux 64bit with the PyMel version that shipped 
with Maya.
