Calibre 0.8.33 installed from source won't start / detect_xml_encoding

[Philantrop]

Am I the only one who gets this when starting calibre 0.8.33 installed from source?

Traceback (most recent call last):

Make sure /usr/lib64/calibre/calibre/ebooks/chardet is deleted.

Thank you, Kovid, that fixed it, indeed.
