 Replying to [comment:21 lutra]:

 Please don't mix too many distinct problems in one ticket
 (v.dissolve,r.null,r.colors!)

 refresh anymore the canvas and the legend after applying a r.colors rule.

 It depends if the raster was added from grass toolbar or browser/module,
 because browser/module are using GDAL but refresh was disabled in raster
 layer (was hack for GRASS). It is already fixed, I have wrote about it
 somewhere.

 already present in the qgis sample dataset, I always get corrupted
 colormaps.

 Works for me.

 Corrupted colormap in raster database or it is not correctly drawn in
 QGIS? Is it realy related to this ticket?

 > *** I'm having an hard time now to remember if the r.colors commands
 also refreshed the raster icon in the legend, I believe that the answer is
 yes.

 The legend is currently hardcoded in qgsrasterlayer for layers using a
 provider.
