Comment:

 Hi,

 I tested again qgis-dev (r12903) installed with osgeo4w (there was
 recently an update of the GRASS packages) and the good news it that
 apparently, now issuing a GRASS command -with no parameters, in the qgis
 GRASS shell- make the program to correctly open the native tcl-tk GRASS
 interface.

 A problem still remains:
 if for some reasons GRASS is launched with the new wxpython interface
 then, when a command (with no paramters) is issued in the qgis GRASS
 shell, an error is returned

 to overcome this problem is enough to re-run GRASS with the tcl-tk
 interface.
