[GRASSLIST:9] breaking polylines2

[Téglásy Örs]

Hi, 
 
 I found the v.segment command to break my polylines (see previous letter), but it doesn't really work for me. Somehow it doesn't find any primitives on the source layer: 
 
 v.segment input=lineament_plines_clean output=lineament_segments llayer=1 
 Building topology ...
 Registering lines: 
 0 primitives registered      
 Building areas: 
 0 areas built      
 0 isles built
 Attaching islands: 
 Attaching centroids: Topology was built.
 Number of nodes     :   0
 Number of primitives:   0
 Number of points    :   0
 Number of lines     :   0
 Number of boundaries:   0
 Number of centroids :   0
 Number of areas     :   0
 Number of isles     :   0
 0  points read from input
 0 points written to output map (0 lost)
 0 lines read from input
 0 lines written to output map (0 lost)
 
 Here are the layer statistics (those plines really exist):
