Sorry I wasn't clear.  What I meant was that there is a problem 
similar to before: -r & -b parameters that work as expected behave 
strangely when I add a -g parameter for barrel correction.

It looks like the red and green channels are remapped correctly, but 
  something different happens to blue.  I can't test here, but maybe 
the barrel distortion isn't being applied to the blue channel.

Thanks, I should have thought of that and could have compared the 
output myself.
