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

 {{{
 i.group ls_ms
 in=lsat7_2002_10 at PERMANENT,lsat7_2002_30 at PERMANENT,lsat7_2002_20 at PERMANENT,lsat7_2002_40 at PERMANENT,lsat7_2002_50 at PERMANENT,lsat7_2002_70 at PERMANENT
 g.region rast=lsat7_2002_70 at 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 ?
