UFRaw sometimes gives inconsistent results. The results varies if the image
was processed by ufraw or ufraw-batch. Sometimes just opening and saving ID
file changes the image.
I wrote a script for systematic testing. It is attached here:
It seems that even the patches I attached to that bug don't fix all these
issues. I will continue with fixing.
Maybe the script could be distributed with UFRaw and eventually extended for
other cameras/options/conf files.
