Comment 22 for bug 1360200

OK, try the build I have uploaded here:

http://download.calibre-ebook.com/betas/

To install them download the appropriate tarball (32 or 64 bit) then, assuming you installed calibre in /opt/calibre, run the following command:

    sudo rm -rf /opt/calibre/* && sudo tar xvf /path/to/downloaded/calibre-tarball.txz -C /opt/calibre
