 Priority:  blocker                    |  Milestone:  7.4.2
Component:  Imagery                    |    Version:  svn-trunk
 Keywords:  i.segment segment library  |        CPU:  Unspecified

 Classifying this as a blocker, as it looks like a serious regression in
 the 7.6 releasebranch.

 With trunk and 7.6 releasebranch:

 {{{
 g.region n=220000 s=219456 w=637033 e=638000 align=ortho_2001_t792_1m -p
 i.group ortho in=ortho_2001_t792_1m
 i.segment ortho thresh=0.01 minsize=1 out=test
 r.info -r test
 min=NULL
 max=NULL
 }}}

 With 7.4.1 I get:

 {{{
 r.info -r test
 min=1
 max=433067
 }}}

 Is this due to the recent changes in the segment library ? Or in i.segment
 ?
