Grasshopper: Surface split (Srfsplit) works different/not anymore?

Hi, I have an existing Grasshopper-Script where I divide a +/- simple surface with the result of a voronoi-operation (ca. 200 cells). This worked fine so far using Srfsplit but with the latest build of RhinoWIP I get an error: “1. Splitting returned no results”

Attached a random example that produces the same error message: (4.9 KB)

Thanks, I see this too. Filed as
