With 

Qt: 4.6.3
KDE Development Platform: 4.4.5 (KDE 4.4.5)
digiKam: 1.2.0

and, more recently

Qt: 4.7.4
KDE Development Platform: 4.7.4 (4.7.4)
digiKam: 1.9.0

I have consistently experienced the same problem when working with DNGs
and JPGs generated by Ricoh GXR modules:

For a given picture, the thumbnail views of both the DNG and of the JPG
files are fine. Import (RAW decoding) of the DNG file is fine too with
Auto-Brightness unchecked. The JPG preview is also fine but the DNG
preview often looks horrible.

No matter whether "Embedded preview loads full-sized images" is checked
or unchecked, DNG previews often look quite different from their JPG
counterparts *AND* from from their raw decoding imports. 

In many cases, DNG previews look like raw decodings with Auto-Brightness
checked. It is as if brightness always was auto-adjusted in DNG
previewing.

This is quite frustrating since it makes DNGs unusable for previewing
and forces me to save both DNGs and JPGs versions of the same picture.

Any idea how to solve this problem ? Any help is highly
appreciated. Best, Nicola
