Just for the heck of it I've just downloaded and installed Ubuntu 17.04 64-bit into a fresh VM too (I can't see anyone saying that Ubuntu is a "weird" choice for someone to install).
The Software Manager reports Scribus as version 1.4.6+dfsg-4.
The Splash Screen shows as version 1.4.6 (but, again, greyscale).
Title Bar shows version as 1.4.6.
In Preferences the Colour Management icon is available and, once CM has been activated, there are many profiles available, all with proper names.
Everything looks fine and dandy there (except the weird greyscale splash screen, like looking at Scribus from the 1940's).
Is it worth someone keeping a list of Linux flavours, which Scribus versions are installed by their Software/Package managers, and whether Scribus works "out of the box"?
So far - in this thread - we have:
* Mint 17.3 - Scribus 1.4.3svn - Unstable Scribus version and possible issues with RGB profiles
* Mint 18.1 - Scribus 1.4.6 - Does not include ICC profiles for colour management (probably)
* Ubuntu 17.04 - Scribus 1.4.6 - All looks fine
I think a better conclusion would be: "Don't trust your software/package manager to have the latest stable version of Scribus and, even if it does, don't trust it to be packaged properly".
