This mailing list is related to the FFmpeg project.
avconv contains several hundred known, user-reported 
bugs that are not reproducible with FFmpeg, please 
understand that we cannot support it.

I suspect you cannot generally concatenate mp3 
files like this (it may work in some cases though), 
please test the concat demuxer:
