Subject: v.surf.rst fails when called from GUI and in command-line mode

Platform: GNU/Linux/i386
grass obtained from: Mirror of Trento site
grass binary for platform: Compiled from Sources
GRASS Version: 6.0 beta2

Calos Henrique Grohmann

code: grass6.0beta2.

When I try to call v.surf.rst from the GUI, when I
click over it I get:

>child process exited abnormally
>child process exited abnormally

>"exec -- v.surf.rst >@ stdout 2>@ stderr"

v"
>    (command bound to event)

and in the terminal:

>ERROR: Required parameter <input> not set:
>    (Name of the vector file with input data).

but how could I give the input if the window didn't even open?
 NOTE: according to Moritz Lennert, it could be a problem with how the module is called by the GUI (it is called via the "run" procedure and not "execute" like v.surf.idw)

and, If I try to call it from the terminal:...

the points are there, inside the region, so how could it not find them???
