Bug report #5730
Trasparent pixels list turns NULLs into "0"

Take a rasters with NULLS (example http://www.faunalia.pt/downloads/declives_pttm06.tar.gz )
with the greyscale colormap is all OK.
Give it a different colormap and the NULLs will be given a colour (not handy).
Then enter the raster properties and in the trasparent pixel list use the "add values from display" tool to pick the NULLs and turn them trasparent -> the NULLs will turn to "0" and so the "0" pixels will become transparent instead of the NULLs ones.
This was observed on both master and 1.7.4
