[GRASS-user] prima di fare una figura da bischero

Hi all.
Sorry for crossposting - I do not know whether the problem resides in
grass or in qgis.
I'm following:
http://trac.osgeo.org/grass/wiki/HowToTestGrass6
All fine, but for the fact that the calculated ndvi map appears on grey
scale, and applying the ndvi color table does not change it.
/usr/lib/grass64/etc/colors/ndvi seems ok:

-1.000 5 24 82
-0.300 5 24 82
-0.180 255 255 255
0.000 255 255 255
0.025 206 197 180
0.075 191 163 124
0.125 179 174 96

0.233 166 195 29
0.266 135 183 3
0.333 121 175 1
0.366 101 163 0

0.550 0 114 0
0.650 0 90 1
0.750 0 73 0
0.850 0 56 0
0.950 0 31 0
1.000 0 0 0

I get these warnings:
Warning: QPainter::setPen: Painter not active
Warning: QPainter::setFont: Painter not active
Warning: QPainter::end: Painter not active, aborted
Warning: QPixmap::scaled: Pixmap is a null pixmap
Warning: Object::connect: No such signal

Warning: Object::connect: No such signal
QgsRasterLayer::editingStopped() in
/storage/build/qgis_unstable/src/app/legend/qgslegend.cpp:549

But I do not know if they are relevant.
Any ideas on how to approach this?
All the best.

I have tested, it is in QGIS. See below...

The resulting NDVI map is colorized in GRASS. But also
here it isn't in QGIS (trunk from yesterday).

I get these warnings:
Warning: QPainter::setPen: Painter not active
Warning: QPainter::setFont: Painter not active
Warning: QPainter::end: Painter not active, aborted
Warning: QPixmap::scaled: Pixmap is a null pixmap
Warning: Object::connect: No such signal

Warning: Object::connect: No such signal

Same messages here.

But I do not know if they are relevant.
Any ideas on how to approach this?

Some QGIS debugging...
