Wolfgang,

I think the quick workaround is to set the rows per strip explicitly:

   gdal_translate -of GTIFF -co "COMPRESS=JPEG" -co BLOCKYSIZE=8 \
            E48-104.tif E48-104j.tif

But the driver should really be picking an appropriate default
strip size. So I'd appreciate your filing a detailed bug report in
Trac on the issue.

Best regards,
