Thank you for the hint, James. Somehow I always thought that this
function is only suitable for separating an existing part from a
feature (never used it though).
Yet, if you cut a polygon with the "Split Parts" tool, the output will
be an invalid geometry (I observed self-intersections). This as well
can not be the intended behavior. I could observe those errors in
simple scratch layers as well as in PostGIS layers.

Has anybody else experienced this behavior?
