           Summary: DNGconverter produces invalid DNG files
           Product: digikam
           Version: unspecified
          Platform: Ubuntu Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: digikam-devel at kde.org
        ReportedBy: dmishd at gmail.com


Version:            (using KDE 4.3.2)
Compiler:          gcc (Ubuntu 4.4.1-4ubuntu8) 4.4.1 
OS:                Linux
Installed from:    Ubuntu Packages

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
