Comment (by martinl):

 From grass-dev ML:

 same problem here:

 Ubuntu 8.10:

 {{{
 ii  gdal-bin                                  1.5.2-4.1~intrepid
 ii  libgdal1-1.5.0                            1.5.2-4.1~intrepid
 ii  libgdal1-1.5.0-grass                      1.5.2-1
 ii  libgdal1-dev                              1.5.2-4.1~intrepid
 }}}
 applyes for GRASS 6.3 (les-ejk ubuntu package) and 6.4 (fresh source
 compilation)

 the problem seems to be in ubuntu gdal package
