[PD] mp3amp segfault

[Nicolas Montgermont]

Hello all,

I am using mp3amp~ on a server and I have a segfault everytime very 
shortly (2-3 sec).
This problem never occurred to me...

pdextended is installed from the available package (without a few 
dependencies)

my system is:
stream_test$ cat /etc/motd
Linux vps-1006620-2877.cp.tsukaeru.ne.jp 2.6.18-028stab069.6 #1 SMP Wed 
May 26 18:10:06 MSD 2010 x86_64 GNU/Linux
Ubuntu 10.04.1 LTS

You can find the log and backtrace of gdb down in this mail. It seems to 
be a libmp3lame error.
The last error is always the same but i find nearly nothing about it on 
the web.
Does someone has any clue on a way of solving that?
thanks in advance,

n
