Description
Attempting to draw layers with color tables from GRASS leads to a total freeze of QGIS. This also occurs if the layers are exported as a geotiff with color tables. The same effect occurs in Windows, although more layers do draw in Windows. Some will render in Windows,but do not respect the color tables (drawn in monochrome). An example color table that always causes a serious crash in Ubuntu (NDVI)

Sorry, I've not tried with the trunk version. I had dependency issues when I last tried to install it from the deb http://int.faunalia.it/~paolo/debian/ unstable/ repository on Ubuntu.

The way as GRASS rasters has completely changed in trunk, so a test would be higly suggested. If the Paolo repository does not work you may want to create the packages yourself, it is pretty easy
this is in Italian

but should be easy to follow the commands

by the way, with the osgeo4w installer you can install the trunk version under Windows.

OK, I successfully built the trunk package (after learning some Italian). The GRASS layers now render, and in double quick time. I am left with a few issues to deal with on my box with some of the python add ons after messing around, but it is clear that the major underlying bug has in fact been dealt with.
Thanks. I apologise again for not trying the latest build before reporting a "bug". Tethys should perhaps be released ASAP. The problem I had does impact the usability of the current release.

Hi, qgis 1.5 will be branched tomorrow.

Replying to lutra:

Sorry, I don't speak Italian. Does that guide say to create a build directory, configure cmake there and then to run dpkg-buildpackage?
Only the latter is necessary. The build directory will be created and configured automatically when dpkg-buildpackage runs.
Does this happens also if you use trunk/1.5?
