Bug 138945

Version:           0.5.5 (using KDE 3.5.5, Debian Package 4:3.5.5a.dfsg.1-5 (4.0))
Compiler:          Target: i486-linux-gnu
OS:                Linux (i686) release 2.6.15-abit-1

When viewing a particular PDF I noted that background "watermark" images
were rendered "dark" instead of "light" and obscured text etc.

To obtain this pdf download from here
http://www.oss.wa.gov.au/documents/FINALGUIDE.pdf

After viewing with linux acroread 5.0.5 or 5.0.8
 (the about box shows both!!!!! on in title other in text)

I confirmed that the PDF rendered correctly.

I would visually consider this to be a severe bug, 
although the severity could be less if the PDF is using an unusual 
method of defining the background.
