[GRASS5] r.in.gdal bug?

[Sören Gebbert]

Dear developers,
im writing a small shell script to download and import Landsat TM Layer and other data availible from NASA WMS service into GRASS.
Im downloading the data with wget and try to import it with r.in.gdal. The downloaded dataformat is geotiff.

But sometime after downloading the data, r.in.gdal produce this error:

ERROR 1: TIFFReadDirectory:/home/soeren/grassdaten/Harz/data/.tmp/AMD64bIT/18773.0/Image_global_mosaic_base_visual_2164_3258: 
Can not read TIFF directory count

The file is a valid tiff file in a directory created with g.tempfile.
Im working with GRASS 6.1-cvs. 
Is this a bug in gdal or in r.in.gdal?
Im using gdal version 1.2.5.

AMD64bIT ~/src/grass6>/usr/local/bin/gdal-config --version
1.2.5

Does anybody else had this problem?

Regards
Soeren
