Inset and offset sometimes gives errors. For example see attached image. If you will use Path->Stroke to path you will have the same result.

It is really important for me to have proper offset results because I'm writing an Gcode tools extension which uses Inkscape offset.
I do not care about calculation time, but really need proper results.
I saw an use_slow_but_correct_offset_method variable that used in offset method. But have not found what it depends on.

Is there any chance to get proper offset results? May be there's a way to rebuild the path before making offset, or use another function to do offset?

PS If I try to use Extensions->Generate from Path->Inset/Outset Halo there are also some errors but on the other side of the path.
By the way, I've found Halo's souse in Extensions dir, but found that it is built in Inkscape souse code.
