Subject: GUI: r.terraflow: the window does not pop up, error printed to terminal

Platform: GNU/Linux/x86
grass obtained from: CVS
grass binary for platform: Compiled from Sources
GRASS Version: 2006-04-12

in d.m:
1. Hydrologic modeling -> Flow accumulation for massive grids (r.terraflow)
2. error in the terminal:

$ r.terraflow December 2003
region size is 241 x 196

ERROR: Required parameter <elev> not set:
    (Input elevation grid).

ERROR: Required parameter <filled> not set:
    (Output (filled) elevation grid).

ERROR: Required parameter <direction> not set:
    (Output direction grid).

ERROR: Required parameter <swatershed> not set:
    (Output sinkwatershed grid).

ERROR: Required parameter <accumulation> not set:
    (Output accumulation grid).

ERROR: Required parameter <tci> not set:
    (Output tci grid).

Description:
 Flow computation for massive grids (Float version).

Usage:
 r.terraflow [-sq] elev=string filled=string direction=string
   swatershed=string accumulation=string tci=string [d8cut=value]
   [memory=value] [STREAM_DIR=string] [stats=string]

Flags:
  -s   SFD (D8) flow (default is MFD)
  -q   Quiet

Parameters:
          elev   Input elevation grid
        filled   Output (filled) elevation grid
     direction   Output direction grid
    swatershed   Output sinkwatershed grid
  accumulation   Output accumulation grid
           tci   Output tci grid
         d8cut   If flow accumulation is larger than this value it is routed using SFD (D8) direction
                 (meaningfull only  for MFD flow)
                 default: infinity
        memory   Main memory size (in MB)
                 default: 300
    STREAM_DIR   Location of intermediate STREAMs
                 default: /var/tmp
         stats   Stats file
                 default: stats.out

If r.terraflow GUI is called from CLI with r.terraflow&, the window pops up, but there is still some unwnated output to the terminal:

$ r.terraflow&
r.terraflow December 2003
region size is 241 x 196
