Well, this is fun.
I have a couple of .ods files, password protected. After installing last Ubuntu updates, including Libreoffice 3.4.5, I can no longer open those files.
I'm using 11.10 x64 Oneiric. Fortunately, my old Ubuntu with the 10.04LTS and Openoffice 3.2 can open those files.
I tried a workaround. I removed the password from the .ods files using Openoffice, moved the files on Oneiric and tried to save them with a password. The error I get is interesting:
General Input/output error.
Does someone has the same problem after the last Libreoffice/Ubuntu update? Before I was perfectly able to open those files.
