           Summary: Editor: Color: Color Effects: Vivid - black areas
                    become reddish

          Platform: Compiled Sources

Version:           1.9.0 (using KDE 4.5.1) 
OS:                Linux

Dark or black parts of the image become red tinted when using option "Color
Effects - Vivid" in digikam Editor.
This behaviour makes the option unusable for most of the photos I think.
