Comment(by jason):
The error is different now too:
{{{
sage: sage: var('x')
x
sage: sage: parametric_plot(vector([x,2*x,3*x^2]), (x,-1,3))
ERROR: An unexpected error occurred while tokenizing input
The following traceback may be corrupted or invalid
The error message is: ('EOF in multi-line statement', (21, 0))
