on canvas artifacts when using absolute colorimetric soft-proofing

Forgot to add:
- SVN r17573
- cairo-1.4.14
- gtk+-2.12.8
- lcms-1.17

Ryan: Why did you mark this as incomplete?

Assigning to JonCruz... Pablo, if possible, would you be willing to attach a file (and a related color profile) to this report in addition to the screenshot?

Sorry for not commenting earlier but I've been busy...

It happens with any old or new file, even when is just the white canvas, so I don't think is necessary to provide a file. The profile I'm using now is the FOGRA Coated 27. Since it is freely available I'm gonna attach it. It happens with any other profile, BTW. The problem persists with r18747, and it's not reduced to only those glitches but also ANY profile is excessively yellowish. I would expect such color on press paper but many papers has a white that turns more to blue... I think that's a bug too.

I've upgraded some of my libs:
- cairo 1.6.4
- gtk+ 2.12.9
- lcms is still at 1.17

I have the same problem of the glitches in the canvas, plus a very bad soft proof, the cyan looks like rgb blue, magenta looks very washed... even when i have the soft proof activated. No matter the icc prodfile.

Is this still a problem now? I can't reproduce this on latest trunk.
