[Libreoffice] Encrypted password -- change?

[Marc Paré]

I am just working on the webpage for the release of 3.4 and on the 
release notes wiki page for LibO 3.4[1] it says:

When the document is encrypted with a password, you can now change the 
password while the document is open, from 
File->Properties->General->Change Password. The button is enabled only 
when the document is encrypted with a password. (Kohei Yoshida)

Could someone check this? I could not get it to work. Maybe I am doing 
something wrong? We'll have to leave it out if this does not work.

Cheers

Marc
