How did you select the paper trsy for your print jobs?
I tested now with up-to-date Saucy and the LibreOffice Writer which comes with it (4.0.2). I have entered some text and printed with LibreOffice's orioginal print dialog (not switched to GTK dialog). The tray I chose in the pop-up which comes up when clicking "Properties" in the print dialog. This way I printed several jobs from different trays and for me the jobs get sent with correct "InputSlot" attributes according to error_log on my print server. So LibreOffice seems to be OK.
