I Julien, thanks for the patch, i've had not time to look at it as i'm 
unsuccessfully trying to patch kpdf/poppler code with changes introduced by 
recently released xpdf 3.02. Helpers in that merging are welcome :-)

Rest assured i'll have a look at your patch when i have more time.

Thanks again.
