Thank you Markus! It works now. Printing the current region could help. Re-wording the manual page may also help. "Unlike most other vector functions, setting the computation region is mandatory in order to deal with infinite regions in the Voronoi diagrams." Or something prominent like that. I read somewhere that vector operations are not affected by the region setting, and had success with v.distance and v.delaunay without ever setting it. The v.voronoi manual says "The bounds of the output map are limited by the current region." but I somehow ignored it as something to worry about later if and when I get some output :-)
