Comment # 41 on bug 905034 from Per Jessen

Using Skanlite - problem persists in Leap422 with latest updates, although I
got a good scan with 150dpi.  I also tried VueScan, which worked just fine. 
Using scanimage - a fairly decent scan in 150dpi, although too dark in the
upper end of the scan.  Wrong colours in 300dpi and in 600dpi.
