 Priority:  normal       |   Milestone:  6.4.3                    
Component:  Vector       |     Version:  svn-releasebranch64

-------------------------+--------------------------------------------------
 I import a dxf without georeferenced information, then scale it with
 v.transform. After that the line length obtained through v.to.db is wrong.
 If I export the line with v.out.ascii and reimport it, the length is
 correct.

 A tarball to reproduce is attached.


 {{{
 tar xzvf bug_grass.tar.gz
 cd bug_grass
 ./reproduce.sh
 }}}

 The script will show the lengths that are much lower than the correct
 length (should be like 3300 for the first line, for instance).
