[Qgis-developer] Bug in QGIS 1.7 raster? Changing transparency values set the 3 RGB bands to band 1?

Hi Devs, 

Forget about my rumblings of yesterday (see below)

The
problem is worse:

- Open a three-band raster into QGIS. It is displayed
OK.
- Open the raster properties window and bang, the three bands (RGB)
are set to Band 1. Resulting in a grey coloured raster if user click
either Apply or OK.

Is that on purpose?

Benoit

Original
message:
"""
 With QGIS 1.7 release r15056 on WinXP Pro. 

 I have a
three-band raster (geotiff) loaded and it displays all-right. Then
 I
open the raster properties window, go to the transparency tab, slide

the transparency ruler and click Apply. The transparency is applied to
the
 raster but the three bands (R,G,B) are all set to band 1 resulting
in a
 black&white (grey) raster! 

 The same behaviour is observed when
I add a transparent pixel and click
 Apply... 

 Can someone confirm
these behaviours? 

 Regards, 
 Benoit
