The test file of the bug 689918 renders with a brown rectangle at top of page, 
which doesn't appear with Adobe.

Well I'm not sure whether the problem is with a shading, but that's very 
likely. It is visible with no banding on ppmraw with default resolution :

..\..\gs-hd\bin\gswin32c.exe -IF:/AFPL/gs-hd/lib;f:\afpl\fonts -dNOPAUSE -
dBATCH -sDEVICE=ppmraw -sOutputFile=cur.ppm decompr-L01-001-K-12345600-
00DSG60k-.pdf

I could minimize the document with removing almost all except the Windows 
logo. 3 characters 'i' near the logo can't remove with Acrobat 8. But it is 
still too big for analyzis. The reduced file appears 3 times longer (36Mb) 
than the original one.

Can't attach the reduced file now due to slow GPRS connection. Will do ASAP.

The problem was also visible with no banding and with -dNOTRANSPARENCY.
