The version you posted is the last release available for Ubuntu on the FreeCAD PPA repository. It is missing 3 bug fixes, the last updated release on Windows and Mac is 0.16.6706
. We plan on updating the PPA as soon as possible, when we do you'll get it through the system updates.
As for your laptop, did you install FreeCAD from the Ubuntu repositories? The reason we created the FreeCAD PPA (I was the one who proposed it years ago, got help from one of the FreeCAD devs wmayer to set it up, then managed it until last year when sgrogan took up the mantle) is the the version proposed in the Ubuntu repositories is always outdated, and is often buggy. One notable exception is Ubuntu 16.10 just released, it's got 0.16 but it's missing the freecad-doc package. I'm guessing we'll have to provide it on our PPA as well.
I am as puzzled by this problem as Willem. I couldn't get the fillet to work either, even on a model built from scratch in PartDesign.
I am wondering how you managed to make it work the first time. Did you create it in an older FreeCAD version? (I'm on the exact same Ubuntu and FreeCAD versions as you)

Just FYI, you can create the main body in one go with a Part Loft of three sketches and the "Ruled" option set to true.
The problem with a shape created with Loft is the the fillet propagates to the next edges even if you don't select them, as your file shows. But in Mongrel_Shark's working model, the fillet is different between the slanted edges (radius of 4 mm) and the straight ones (radius of 2 mm). What's more puzzling, fillets should propagate to the next edges only when they are tangent, which is not the case here.
Very strange indeed.
EDIT: there's another problem with using a Part Loft. The generated faces between the sketches are not considered planar (even if they really are), but as BSpline surfaces. The result is that it is not possible to map sketches to them.
