When I use DNG converter it produces DNG files which are not valid. The
camera is a Canon EOS 300D producing .CRW format files. When I run
DNGconverter from the command line no errors are reported. Using file it
seems to be OK:

$ file CRW_4212.dng
CRW_4212.dng: TIFF image data, little-endian

but when I try to view it in Eye of Gnome (eog) I get the error message:

Could not load image 'CRW_4212.dng'.
Failed to load TIFF image: ColorMatrix1: Rational with zero denominator (num = 
0)

I'm attaching a sample image in CRW format, and the resulting DNG file.

DNGconverter worked fine for me in Jaunty (which was also 64 bit).

The karmic version of kipi-plugins is 0.7.0
