I have run into this same problem. What I have discovered is that during the installation, or initial execution of Calibre, all files in /usr/share/mime are set to rw-------. I was able to restore my desktop after running
Code:
sudo find /usr/share/mime -type f -exec chmod 644 {} \;
So, there is a problem in the installation that is either resetting file permissions in /usr/share/mime, or replacing the existing files with files that are 600 not 644.
