It works fine her with libav 9.11. Could you post the output of running avconv -y -i 'Randy vs The Braindrillerz LIVE @ FOOTWORXX 10.03.2012-_GT_KUTgwIc.mp4' -vn -acodec libmp3lame -q:a 0 'Randy vs The Braindrillerz LIVE @ FOOTWORXX 10.03.2012-_GT_KUTgwIc.mp3' (the command that is printed)?

Audio encoding failed

After googling a bit it seems like this was a known bug in lame 3.98, however, on my system I have libmp3lame0 3.99.5+repack1-3 (debian ) installed so I'm not sure it's the same issue.

I don't have any system with this issue anymore so I'm closing this. If someone happens to run into the same issue feel free to open a new issue for this.
