i.segment.hierarchical: RuntimeError: Execution of subprocesses was not successful

Reported by: mlennert Owned by: grass-dev@…
Priority: normal Milestone: 7.0.5
Component: Addons Version: unspecified
Keywords: i.segment.hierarchical GridModule Cc:
CPU: Unspecified Platform: Unspecified

Description

I just can't get i.segment.hierarchical to run in parallel processing with the GridModule: 

i.group ls_ms in=lsat7_2002_10@PERMANENT,lsat7_2002_30@PERMANENT,lsat7_2002_20@PERMANENT,lsat7_2002_40@PERMANENT,lsat7_2002_50@PERMANENT,lsat7_2002_70@PERMANENT
g.region rast=lsat7_2002_70@PERMANENT
i.segment.hierarchical ls_ms threshold=0.1 output=ls_ms_seg width=200 height=200 overlap=10

gives me 

Traceback (most recent call last):
  File "/home/mlennert/.grass7/addons/scripts/i.segment.hierarchical", line 252, in <module>
    SEG.run()
  File "/data/home/mlennert/SRC/GRASS/grass_trunk/dist.x86_64-pc-linux-gnu/etc/python/grass/pygrass/modules/grid/grid.py", line 553, in run
    raise RuntimeError(_("Execution of subprocesses was not successful"))
RuntimeError: Execution of subprocesses was not successful

I don't really know how to start debugging this. Could someone point me in the right direction ?
