v.support problem

[Thomas Wilke]

Dear GRASS users

after importing Arc-Ungenerate-Files as polygons into GRASS with
v.in.arc I try
to build the topology of the polygons with v.support. Most of the
polygons are build correctly but for a small number I get a message like
this:

PNT_TO_AREA failed: (3574062.500000, 5717337.500000) (Category 19000)

What is the reason for this message? And is there a solution for this
problem?

Thanks,

Thomas
