Yes, I have found similar problems recently, unfortunately, I haven't
had the time to fix them yet. The module that we use to calculate the
tessellation is not ideal, and as soon as it makes its way into GEOS,
I'd like to use the JTS voronoi polygons solution in QGIS. Please file
a ticket in the bug tracker for now, and I'll see if I can work out a
workaround. In the mean time, if someone else can get to this sooner,
feel free to submit a patch as well!

Cheers,

Carson
