When I open your eps file with ghostscript, I can see the problem. I'm about 95% sure that this is related to the ghostscript not correctly rendering the line. In your ghostscript viewer, turn off "antialiasing" then you will see straight line (of course w/o antialiasing).
This seems to be a known problem that has recently been fixed http://www.ghostscript.com/doc/current/Changes.htm (see the entry of 2010-04-07T13:13:57.741241Z Robin Watts) It only happens when you use "round" join style. So, change your rc file (or any other setting) not to use "round" style. In case you must use "round" style, I guess you'd better upgrade your ghostscript.
