Radim:
> Try the same directly with v.in.ascii.

Same result. (sample file & DEBUG=5 stderr log attached; stdout is as above)

also

G57> d.vect test8novTRK
WARNING: Cannot display areas, topology not available

[input file (eg attached) only contains lines, they draw ok]



> What files are in vectors directory.

$ ls vector/test8novTRK/
coor  dbln  head  hist



> Does it help to run v.build?

Yes. After running v.build everything works as expected.

[not attached file..]

G57> v.build test8novTRK
Building topology ...
152 primitives registered
0 areas built      8%
0 isles built
Topology was built.
Number of nodes     :   240
Number of primitives:   152
Number of points    :   0
Number of lines     :   152
Number of boundaries:   0
Number of centroids :   0
Number of areas     :   0
Number of isles     :   0



[0 areas built      8%] ????

Then these files exist:

G57>  ls vector/test8novTRK/
cidx  coor  dbln  head  hist  sidx  topo



thanks, I think v.in|out.ascii modes are much less confusing now.
