I see that this error only appears in 8-bit mode (settings->Configure 
digiKam->IO files->16 bits... *un*checked). If 16 bits... is checked this 
error doesn't occour.

Also, to reproduce it's not really necessary to change the picture as told in 
Step 2. It suffices to open a CR2-file and "Save as..." jpg, for example.

The error occurs only when starting with a CR2-file here (I don't know about 
other raw files, I have only CR2).

Doing the same procedure but starting with a jpg or png or tiff... doesn't 
produce this problem.

I have updated svn few minutes ago, just to be sure the error still occurs...
