Error with new installation of youtube-dl

[Dreeg]

Hi all,
on RPi2 with Raspbian I just installed youtube-dl and when I try to DL a videos the software return me this error:

Traceback (most recent call last):
File "/usr/bin/youtube-dl", line 75, in
import xml.etree.ElementTree
ValueError: bad marshal data (unknown type code)

Can you run the following command:

$ python -c 'import xml.etree.ElementTree as ET; print(ET)'                   

The result should look like:

<module 'xml.etree.ElementTree' from '/usr/lib/python3.4/xml/etree/ElementTree.py'>

The result of

python -c 'import xml.etree.ElementTree as ET; print(ET)'

is

Traceback (most recent call last):
  File "<string>", line 1, in <module>
ValueError: bad marshal data (unknown type code)

This should be a Raspbian issue rather than youtube-dl's problem. Try to ask for help on RPi forums.
