Bug report - Some support material generated twice.

[Aggresive]

The printer prints over the same support material twice, pushing the filament into the perimeter wall, this welds and becomes very difficult to remove.

It also seems that the support material is generated too close to the perimeter walls, (although this is removed quite easily with a bit of force).

The problem I am having at the moment is with the nut traps at the bottom of the part below, particularly the right hand ones on the edge of the part. The ones to the left seem to be ok.

I don't know what the usual way of uploading files is, but I've uploaded the gcode and original stl to my skydrive.

I increased distance between support material and object, but I can't understand or locate the double extrusion at a first glance. Would you be so kind to help me locate the issue? i.e. layer number and position of the double extrusion? Thank you!

Hi, I've uploaded a screen from printrun to the skydrive; upon closer inspection, it seems like there is two very short lines of support generated, very close together (similar to the gap between perimeters), but not at the same place like I thought.

Since the change, slic3r does not seem to generate support anymore. even on the large section to the left of the problematic nut traps. It displays that it is generating support material, however, when the g-code is opened in pronterface, there are no support extrusions.
