savefig eps error

today i produced an image that failed to save to eps.
i can save the file in pdf, but i get the same error if i try to use
pdf2ps. png works too, but its not vector.

not sure if its important, but the image has 401 lines, with 500 points

the image is produced from a bunch of data files and im not sure how to
most effectively send this over email ( in case you all wanted to
re-produced the error).

the main error is

Error: /nocurrentpoint in --lineto--

here is the whole error
