import pyx
orig_p = pyx.path.line(0,0,5,5)
par_p = pyx.deformer.parallel(0).deform(orig_p)
This example produces an AttributeError which should not happen.
It is caused by the method parallel.deformsubpath which returns
a wrong type if the distance is too small.
I think the attached patch can remedy this deficiency.
