Comment # 32 on bug 905034 from Per Jessen

I have just yesterday observed this issue on Leap421.  I have a test system
which I have been using with my scanner for a good few months, no problems,
colours all fine.  Yesterday I decided to re-install it, also Leap421+updates,
and now I get poor/bad colours on scans. 
Because the hardware didn't change and I'm pretty certain the software didn't
either (can't be 100% certain), it seems it could be some sort of
initialisation issue?
