[GRASS-user] bug?: v.to.db wrong area

[Achim Kisseler]

Hi,

I am using

v.to.db map=af_grid option=area columns=area type=centroid units=kilometers

(in GRASS65 opensuse 11.1 64)

to calculate the area size. Some of the areas are very wrong. Its a grid
in lat-lon, where areas should be nearly equal in size.

Is this a known bug? I don't guess so.
Do I something wrong?

Thanks,
Achim

PS:
already did v.clean, r.mask -r (<- should not be have an effect)
