 hopefully fixed in r58512 (devbr6).

 The command breaks both lines (1 and 2)

 {{{
 v.edit map=network tool=break coords=33.6708333333333,16.9041666666667
 }}}

 You want probably break only line with id 1

 {{{
 v.edit map=network tool=break coords=33.6708333333333,16.9041666666667
 id=1
 }}}

 Another option would be to break lines on intersections

 {{{
 v.clean in=network out=network_break tool=break
 }}}

 or

 {{{
 v.edit map=network tool=break id=1-9999
 }}}

 assuming that the map has less them 10e3 lines.
