I just ran into the same bug. It's not in the pointsfile, but rather
that v.out.ascii makes a blanks line in the header of the generated
vector ascii file. Then, v.transform aborts when it encounters the
blank line.
 
I don't know which module is buggy here.

Yes, but even then, the point is that v.transform requires:
 
        v.out.ascii
        v.transform
        v.in.ascii
 
rather than simply working with the vector maps in the database.
 
Also, I'm know running into problems with v.transform. It may be
because my XY data from DXF has negative coordinates. The v.transform
documentation specifically states that negative numbers have never
been tested. I need to get this working, so I may have a patch
together soon, (and it'll finally be time for me to ask for CVS write
access).

v.transform changed to read/write vector binary files.
