could it be that you there are to much overlapping blob components at the
start/end section ?

to put it other words: for a closed path you have n components and n section 
(between the components) while for an open path you just have n-1 sections.
So try to remove the last blob component  or adjust the step-width and see if 
there is still this artifact.
