The same. Because 'gdalinfo --formats' is missing GRASS.....

Ok, that is the problem and gets GRASS to show up in 'gdalinfo --formats':

mkdir /usr/lib/gdalplugins
ln -s /usr/lib/gdal_GRASS.so /usr/lib/gdalplugins/gdal_GRASS.so


If doing this is against Debian policy then the above code in Debian's 
GDAL package needs to be patched to use perhaps '/usr/lib/libgdal1' or 
just  '/usr/lib'. (I'm not sure if it must be /usr/lib/package-name, but 
everything else is /usr/lib/dir/ seems to be like that)


** So the libgdal1-grass package is broken with GDAL 1.2.6.

It does.

I still get a segfault, both with r.out.gdal and loading a GRASS raster into
QGIS, but progress has been made today.



thanks,
