Do we have a namespace collision with GDAL?

What is the output of r.external.out -p ?

This error can only happen with PREDICTOR=2 as a GTiff creation option.

[neteler]

Oh, I completely forgot that I had set r.external.out some months ago in that mapset.

r.external.out -p
directory: /home/neteler/tmp
extension: .tif
format: GTiff
options: COMPRESS=LZW,PREDICTOR=2

It would be great to improve the error message above with a related hint to check r.external.out.
