I wondered whether the problem happened with all the profiles that Adobe make available for free to end users (https://www.adobe.com/support/downloads/detail.jsp?ftpID=4074), so I tried it with all of the CMYK profiles provided in the zip file and found that the problem occurs with the following 7 out of 14:

Coated-FOGRA27--ISO-12647-2:2004-
Coated-FOGRA39--ISO-12647-2:2004-
Coated-GRACoL-2006--12647-2:2004-
Uncoated-FOGRA29--ISO-12647-2:2004-
US-Web-Coated--SWOP--v2
U.S.-Web-Uncoated-v2
Web-Coated-FOGRA28--ISO-12647-2:2004

I also tried the following profile, downloaded from http://www.colormanagement.org/en/isoprofile.html, and found that the problem occurs with this one too:

coated_FOGRA39_GCR_bas.icc (this is the actual profile name, as well as the file name).

As mentioned above, changing the name with a hex editor solves the problem for solid colours, but not for gradients.

When the problem occurs, the selected profile on the CMS tab jumps back to the last one that works fine, e.g. '<none>' or 'Japan Color 2001 Coated' (also in the Adobe profile pack).

I did not try any of the 8 Adobe RGB profiles also in the same pack.

This bug report is 5 years old and really ought to be addressed. Comment #10 from 2013 seems to acknowledge that the problem is in Inkscape's code, but there is no follow-up.

I'm working on CD artwork for an established artist at the moment and have to recreate some of the artwork I have been supplied with as it's not usable in its current form (wrong dimensions and in RGB). I don't have access to Illustrator, PhotoShop etc., and even if I did, I make a point of being able to do this purely with open source software. I've done a few in the past, using Scribus, Inkscape, GIMP and Krita, but it is not exactly easy, largely due to the lack of (proper) CMYK support in Inkscape and GIMP. Having this particular problem solved would go a long way in getting designs from Inkscape into Scribus for CMYK professional printing. This bug is currently a major hindrance in trying to complete this artwork.

I'm using Inkscape 0.91 r13725 on Arch Linux.
