[GRASS-user] r.to.vect.lines addon not working

[Carlo Cormio]

Hi all,

I'm facing problems with r.to.vect.lines addon module on different 
platforms (Fedora 23, Windows 10).

I compiled GRASS GIS 7 from svn source (updated right now to GRASS GIS 
7.0.5svn R68347), see configuration at the end of the e-mail), then 
installed the addon using g.extension. Installing works fine, but when I 
run the command (either from GUI or command line) it provides me the 
following error:

--------------------

Traceback (most recent call last):
   File
"/usr/local/grass-7.0.4svn/gui/wxpython/gui_core/prompt.py",
line 263, in OnItemSelected

self.cmdDesc = gtask.parse_interface(cmd)
   File
"/usr/local/grass-7.0.4svn/etc/python/grass/script/task.py",
line 520, in parse_interface

"<{name}> module: {error}").format(name=name, error=error))
grass.exceptions
.
ScriptError
:
Cannot parse interface description of<r.to.vect.lines>
module: not well-formed (invalid token): line 17, column 19

---------------------

The last two lines also appear in grass shell when I launch GRASS 7.

I have no ideas about the origin of such error, any idea?

Thank you,

Carlo
