I'm currently working in tiff loader in digiKam core to support better 
exif/makernote/iptc during saving from editor (TIFF/EP compliant).

I cannot reproduce this thumb problem with current implementation. digikam 
kioslave witch perform thumbnails rendering support 16 bits images (that 
konqueror don't support very well).

Are you sure that you kioslave used by digiKam is really from 0.9.0 not 0.8.x 
(when you mix both versions on a system for example)

In editor, Toogle Color depth using 'Fix/Color/depth' menu.

An advanced saving dialog with options is planed for the future. There is a 
file in B.K.O.
