It works to me... at least using 1.15.  But at that point, and since the error message says:

"Output  profile is operating on wrong colorspace"

Have you double checked the profile is really operating on CMY space?  Maybe 
you are trying to do that with a CMYK profile? 

If the profile is correctly using CMY, please give a try to 1.15, chances are that is 
already fixed.http://www.littlecms.com/lcms-1.15.tar.gz

If none works, please send me the profile and I will take a look.
