I just realize that I cannot download a playlist anymore

[dnaggie]

hello there great team of youtube-dl, first of all fanx for the great and powerful tool, which i find so helpful.
my problem recently is, after upgrading from ubuuntu 12 to 14, I cannot download a playlist, like lots of videos at the same time but i can download single videos. I don't know what could be the problem.

Post the full output you get when running with --verbose option.
