Hi,
You probably know this, but just in case, are you all using the same bounding box model in Inkscape ?
- Edit -> Preferences -> Tools -> Bounding box model to use -> Geometric (ignores stroke width) or Visual.

OK. Thanks.
But ... why would you call segment surface on this face ?

Slice_group = CompoundTools.Explode.explodeCompound(f) # Creation of "Exploded Slice" Here, Slice_group is a tuple : ( group_object , list_slice_objects ) Be careful, group_object can be None, if there is only 1 slice part. So you'd better use the slice objects from list_slice_objects . These are A...

JoinCurve is exactly aligned with the face border, on the left side : this is looking for troubles.
You should make trim curves that extend beyond the face to trim.

Maybe :

Your tessellation values are probably too high :

Not that new : 2015 !!!

But I had never used it yet.

The name of the object has changed.
It should work by replacing "DWire" with "Wire" in the first line of the code :

I assume there is no other way than a cut or a common to check if two objects are colliding and not adjacent? Because it also seems quite an expensive operation for what you want to know. (If you know that one point is inside of the other object you already know sufficient in fact). Maybe Shape.pro...

Both G and C continuities exist.
Here is a pretty good explanation :
