[Gdal-dev] error 1: JPEGSetupEncode:RowsPerStrip must be multiple of 8 for JPEG

[WolfgangZ]

Hello,

I'm trying to convert some TIFFS so that the compression is JPEG.
The source image was a tiff with a color palette. I used pct2rgb to 
convert it first.

D:\todonew>gdal_translate -of GTIFF -co "COMPRESS=JPEG" E48-104.tif 
E48-104j.tif
Input file size is 8000, 5778
0ERROR 1: JPEGSetupEncode:RowsPerStrip must be multiple of 8 for JPEG
ERROR 1: TIFFWriteScanline failed.

I'm using the FWTools 1.3.5 on WinXP.

Thanks for any help
Wolfgang

PS: gdalinfo on the input file gives:
