Comment 9 for bug 155125

I forced it to overwrite openoffice.org-common's intro.bmp and that seems to work fine:

sudo dpkg --force-overwrite -i /var/cache/apt/archives/broffice.org_1%3a2.3.0-1ubuntu5.1_all.deb

That way I got back my father's links to broffice and the ability to double-click any of his odt files :)
