Yep, I'm using that (sRGB-IEC...)

Same setting, just that I use Foagra Coated for CMYK.

Here you have the choice: use no ICC profiles or use ICC profiles for solid
color and images:

* using no profiles gives me a plain blue output, that's obviously a bug,
maybe related to endianness on PPC
* using profiles gives me output comparable to the tiff image

I'm not really sure what happens if you uncheck "use ICC profiles for
images".

No
