Yesterday I've installed a new version of LibreOffice (4.1) and tried to open one of my documents. This document is protected with a password. LibreOffice told to me, that password was incorrect. I tried to re-enter the password with a same result. A previous version of LO opened this document correctly. The last version of OpenOffice managed this task too. Then I tried to create a new document and to save it with a password. I've got a «general input/output error». This problem was registered both on Xubuntu 12.04 and Lubuntu 13.04 Beta. On WinXP this problem was not registered.
