just tested the example from the manual  with:
GRASS version: 7.1.svn
GRASS SVN revision: 67197
Build date: 2015-12-17
Build platform: x86_64-w64-mingw32
Platform: Windows-7-6.1.7601-SP1 (OSGeo4W)
it works as expected, the attribute table of the lines is in the connected
node-line-vector layer. can you test it with the NC sample data set ?
