mmmm, I had splitted it, and in fact this algorithm just calls the
angle option, but it still complains
This is your command line
v.buffer input=tmp1338388935286 angle=90 tolerance=0.01 -s -c
output=output --overwrite
and it says
ERRORE: Select a buffer distance/minordistance/angle or column, but not
both.
But it's only passing an angle, not any of the other options!!!. Or
you are not supposed to use tolerance with the angle option?
Any GRASS expert can help?

Actually, the relevant part of the code is this:
if (((dista_opt->answer || buffer_opt->answer) && bufcol_opt->answer) ||
(!(dista_opt->answer || buffer_opt->answer || bufcol_opt->answer)))
G_fatal_error(_("Select a buffer distance/minordistance/angle "
"or column, but not both."));
which means that you need either a buffer distance or a buffer column, but not neither or both of these. I guess the "distance/minordistance/angle" part was meant to signal that distance could be combined with minordistance and or angle, but I agree that the message is not very clear in that way. I think it should rather read something like this:
"You must indicate either a buffer distance or column, but not both."
An angle on its own could not define a buffer, so it would be useless.
