clive fails to download any videos from Youtube

[Moritz]

When trying to download videos from youtube with clive, I get something like this:

$ clive http://www.youtube.com/watch?v=jEzgzMzgekU
WARNING: gnome-keyring:: couldn't connect to: /tmp/keyring-EiZ8QI/pkcs11: No such file or directory
fetch http://www.youtube.com/watch?v=jEzgzMzgekU ...done.
verify video link ...
error: Unknown error (http/403)
        (in cleanup) cannot access `DESTROY' field in class clive::Video at /usr/share/perl5/clive/App.pm line 106

This is independent of the video URL. Downloading the same video, from the same network, with clive 2.3.3-2 from Debian works fine.

I have no idea if that matters, but the host has fine IPv4 and IPv6 connectivity, and at least the IPv4 connection is NATted. The same applies to the Debian box with which the download works.

With --debug I get this output:

WARNING: gnome-keyring:: couldn't connect to: /tmp/keyring-EiZ8QI/pkcs11: No such file or directory
