Won't fix is from upstream. Their version, from which the Ubuntu version is derived, doesn't show the bug, so the upstream maintainers won't be fixing it themselves.
So far although rated high in importance the bug isn't assigned to anyone involved in Ubuntu to fix. How you fix on your system I can't advise as I don't know whether you are running oneiric with the proposed repository active or pangolin... However, for me I just open my encrypted documents on a machine running a pre-bug version for now. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to libreoffice in Ubuntu. https://bugs.launchpad.net/bugs/919659 Title: [Downstream] Can't open/save spreadsheet with password Status in LibreOffice Productivity Suite: Won't Fix Status in “libreoffice” package in Ubuntu: Triaged Bug description: 1) lsb_release -rd Description: Ubuntu 11.10 Release: 11.10 2) apt-cache policy libreoffice-calc libreoffice-calc: Instalado: 1:3.4.5-0ubuntu1 Candidato: 1:3.4.5-0ubuntu1 Tabela de versão: *** 1:3.4.5-0ubuntu1 0 500 http://br.archive.ubuntu.com/ubuntu/ oneiric-proposed/main amd64 Packages 100 /var/lib/dpkg/status 1:3.4.4-0ubuntu1 0 500 http://br.archive.ubuntu.com/ubuntu/ oneiric-updates/main amd64 Packages 1:3.4.3-3ubuntu2 0 500 http://br.archive.ubuntu.com/ubuntu/ oneiric/main amd64 Packages 3) What is expected to happen in Libreoffice Writer via the Terminal: cd ~/Desktop && wget https://bugs.launchpad.net/ubuntu/+source/libreoffice/+bug/919659/+attachment/2700639/+files/test.odt && lowriter -nologo test.odt type in the password: password and the file opens successfully, as it does in 3.4.4. 4) What happens instead is that the file does not open and a message pops up: LibreOffice 3.4 The password is incorrect.
