Leica M8 DNG thumbnail problems

Jeff S-5
Hello,

Has anyone experienced this problem before? My DNG raw
thumbnails have been messed up ever since I upgraded
from Kubuntu Dapper Drake to Edgy Eft. NEF raw images
and JPEGs still display okay.

This is what I am seeing:
http://csd.net/~4season/dng_thumbnails.jpg

I was previously using Achim Bohnet's 0.90 packages on
Dapper Drake, and thumbnails looked fine.

But I did a clean install of Edgy Eft, installed
Achim's 0.90 packages for Edgy, and that's when I
noticed the problem with the thumbnails.

I have rebuilt all thumbnails, but this hasn't helped.

I also tried upgrading to Achim's 0.91-rc1 packages,
but the thumbnails still look strange.

About digiKam reports:
digiKam 0.9.1-rc1 (Using KDE 3.5.5)
Using Kipi library version 0.1.5
Using KExiv2 library version 0.1.0
Using Exiv2 library version 0.12.0
Using PNG library version 1.2.8
Using Gphoto2 library version 2.2.1

Jeff

Jeff,
 
digiKam 0.9.0 and 0.9.1 use dcraw 8.54 to extract DNG thumbnail. future digiKam 0.9.2 will use libkdcraw including dcraw 8.60 witch normally fix the problem.
 
Please send me a DNG file sample to test on my computer. Please use my e-mail "caulier dot gilles at gmail dot com" thanks in advance

With this mornings svn I get
under "Configure digikam"/"RAW decoding"
dcraw version 8.41?
("About digiKam" is essentially the same as Jeff's, apart
from digiKam 0.9.1-rc2 (Using KDE 3.5.5))

yes,you have right, 8.41 is used in digikam 0.9.0 and 0.9.1. I'm little perturbated by my new computer (:=)))

Jeff,

current implementation of digiKam from trunk  (next 0.9.2 release) use
libkdcraw shared lib. dcraw 8.60 is used internally and your DNG thumbs
problem is fixed now...
