 Hi, I updated to r12891 and this are my first quick notes. I'll do the
 tests you suggest tomorrow. I haven't read your answers with attention so
 please forgive me if I'm repeating something is already known/obvious.

 > Does it displays always with the same colors or they are random?

 always the same.

 First a good news, removing the rasters form the legend under Vista does
 not crash qgis anymore. So... probably the problem that originated this
 ticket is really fixed.

 Nevertheless there are side effects that I'll report here even if they are
 more about #2028 and #2078. Tomorrow I'll copy the notes also to the
 respective tickets.

 Then:

 a) On both XP and Vista when I import (v.in) the following raster (single
 band)

 http://www.faunalia.it/qgis/data/srtm30-relief.zip

 qgis always renders the image with the colors scrambled.

 b) On both XP and Vista when I import (v.in) the following raster (multi
 band)

 http://www.faunalia.it/qgis/data/landsat-mosaic-test.zip

 qgis renders the image fine.

 c) The raster (single band) in the mapset in the qgis sample dataset is
 rendered fine on both xp and Vista

 d) in all cases a) b) and c) if the "value tool" pluign is active it
 returns a python error. It used to work with GRASS rasters.

 e) On both XP and Vista, when applying a r.colors rule on b) it works fine
 and it refreshes correctly. When applying a r.colors rule on c) it renders
 with colors scrambled.

 Could this mean that there is a problem with single band images?
