RGB sabres just turn white

[sirbubbles]

Hello, I'm running JA++ with the openjk project under Ubuntu 15.04. The problem I'm having is that whenever I choose a custom sabre colour from the profile menu, it just shows up as a plain white colour in game. The custom colour I choose shows up just fine in the menu, but no joy once I exit. Any ideas as to what could be happening? It's the linux version of both openjk and JA++, with nvidia drivers installed.
