Yes, The last time I saw that one the resolution was to increase perimeter overlap.
It looks like your infill overlap is not high enough over your perimeters. It may be an unfortunate number rounding issue for that direction/case on infill. The rest of the fill to perimeters look like they are just touching- but fine. Skeinforge has a setting for that, I cannot remember about Slic3r.
I only used slic3r for a little while until I got to the point in my machine calibration where I wanted more control. But you go from like 20 settings to like 100, so a little good and bad- mostly good, but more work.
