[magick-users] error converting tiff

[Julius Minka]

Hello,

I have a problem converting tiff to jpeg:

convert  ttt.tif ttt.jpg
convert: ttt.tif: Bad value 1 for "ExtraSamples". `_TIFFVSetField'.

file ttt.tif 
ttt.tif: TIFF image data, little-endian

Similar behavior with Gimp, however on Windows I am able to see the
image.

Linux: Ubuntu Feisty 
Version: ImageMagick 6.2.4 02/16/07 Q16

How can I convert the image? I can provide you with the image.

thanks,
julius
