Comment 6 for bug 919176

it appears that there are two (or more) separate bugs shown here.

a partial fix for one has been committed to bzr rev 11094.
this will properly display the gradient in the logo at the bottom right hand corner of page 7 of FR_plaquette ferroviaire.pdf. It also makes visible a long curved horizontal line just above the logo. There is still a problem with a rounded rectangle at the bottom left, which is not displayed completely.
