Using the old metadata file (in this case: LE71840312002041SGS00_MTLold.txt) 
works fine.

GRASS 6.4.3svn (wgs84_utm_z34_test):~ > r.info -r B.DOS1.ToCR.61
min=158.263805493393
max=338.623091571347

GRASS 6.4.3svn (wgs84_utm_z34_test):~ > r.info -r B.DOS1.ToCR.62
min=240.06999848884
max=322.080084447704


I guess it is a bug (something that got away in latest updates of 
i.landsat.toar towards the newer metadata file).  Will try to check further... 
not today though, deadlines approaching.

Best, Nikos
