[GRASS-user] v.edit break ERROR: Attempt to delete dead feature

[achim]

Hi all,

I try to break a couple of lines on specified points (nodes in a network
to get separated lines).

I do this with for one example-point successfully:
v.edit map=laflo_break at achim layer=1 type=line tool=break ids=0-9999999
 thresh=-1,0.000001,0.000001 coords=32.6958333333333,8.67083333333333

but doing this with a list of more than 6 coors or having the same coor
twice in the list,  I get the "Attempt to delete dead feature"-error.

Is there a limiting number of coords for v.edit or is it something else?
What does grass try when it "Attempt to delete dead feature"

Thanks,
Achim
