Comment (by FredTester):

 It seems to work. Thank you. I applied your second patch, but not the
 first one.

 I will test further, but meanwhile I assembled some LUT test files. They
 are here:
 http://www.datafilehost.com/d/b9643ffa

 There are three parts in the zip file:
 - 3 .cube files, that I use for my own programming needs
   (plain.cube, lowR_normalG_highB.cube, really3D.cube)
 - these 3 are converted to other formats using RedGiant LUTBuddy
 - then there is a bigger collection of LUT files that I found on the web

 And still unexplored are the possibilities of the ARRI LUT Generator
