[scribus] Linux Ubuntu & Mint: Export in PDF in CMYK color mode (printer) is not giving a correct result

[Eric Dodémont]

I just investigated a little bit more, and with the latest Ubuntu official
package (version 1.4.4), I can find the "Enable/Disable Color Management"
button in the lower/right window corner, but I cannot find anymore the
"Color Management" tab in the preferences... There is really something
missing!

I found the following unofficial package (version 1.4.5):
scribus_1.4.5+dfsg1-5~0utopic_amd64.deb.

With that package, the "Color Management" tab is present in the
preferences, and the RGB to CMYK conversion works correctly with the color
management disabled. I tested it in Linux Ubuntu 14.10 and Mint 17.1.
