This is odd... I just reproduced the issue again with a vanilla Ubuntu 12.04 beta image from ubuntu.com (ubuntu-12.04-beta2-desktop-amd64.iso): I started the ISO in a virtual machine, used "Try Ubuntu" mode and navigated to this bug report. On opening the attachment I got the "Read-Error". The beta still has 3.5.1-1ubuntu1, therefore I re-ran the ISO, this time doing a proper installation (English language, nothing fancy). The libreoffice packages have been automatically updated during the installation (i.e. they are now 3.5.2-2ubuntu1), but again -- "Read-Error" on the above file.
