Hello, I had same problem with my calibre installation. During web search for possible reason I found working solution on this page http://www.mobileread.com/forums/showthread.php?p=1902043#post1902043.
In order to fix calibre installation you must remove /usr/lib64/calibre/calibre/ebooks/chardet (/usr/lib/calibre/calibre/ebooks/chardet for 32 bit systems) directory. -- Piotr Marnik -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
