vignette pink color cast

Do you have the same problem with the vignette tool? This happened since version 6.0 but I thought it was my fault but it happens with all images that have a bright content.

When I apply a dark vignette to an image with bright content (blown out highlights - no color information) let's say a wedding bride and groom then the corners get an annoying purple/pink color cast. I don't know what causes this effect.

thanks
Daniel

  Maybe you have a Canon and/or use a low ISO setting?

  Yes I have a Canon, the 1D Mark IV and I was on ISO 320. The pink color cast appeared since Capture One Pro 6.0. Also when using the exposure tool all the way down to -3 this color cast becomes visible. It must have something to do how blown highlights are interpreted by Capture One 6.0.
  
  I've checked my files with Adobe Camera RAW and Lightroom 3 and there is no pink color cast.

  Please submit a support case with a RAW file as soon as possible.
  This is something that has to be corrected in Capture One's image core.

  Yes in 6.3 the problem still exists. The guys from the support told me that it will be fixed but they can't say when.
  Until then I have to mask out the areas and decrease saturation to get rid of the magenta cast. It's not good for every picture because you can see the B&W area then.

  I have managed to reduce the effect via an advanced color edit now.
