I noticed that libreoffice_5.2.7-1~bpo8+1 failed to build for i386 arch (and it was same with libreoffice_5.2.6-1~bpo8+1, so last available version for jessie-backports/i386 is 5.2.5-1~bpo8+1), see
https://buildd.debian.org/status/package.php?p=libreoffice&suite=jessie-backports (No security issies was mentioned in 5.2.6/5.2.7 changelog, so it is probably not very *terrible* *urgent* problem ^_^, but it would be nice if it was fixed).
