Hi all :
I got this two geometrical entity:
Ellipse: Center Point : (-22.1368,132.821) , horizontalRadius
Axi=641.625758588, Mino Axi=561.422256982
Arc\Circle: Center Point : (-370.288,132.821) , Radius 256.867341765 ,
StartAngle=0, EndAngle=6.28318530718
if I intersect this two entity I got the following error:
>>> e=geo.Ellipse(geo.Point(-22.1368,132.821),641.625758588,561.422256982)
>>> c=geo.Circle(geo.Point(-370.288,132.821),256.867341765)
>>> e.intersection(c)

I dose this test with sympy 0.7.rc1
