Unfortunately, I cannot as the server is in a remote location. I also
have to read about crash dumps to establish which file exactly cuases
the crash. I have too much debugging but I usually see
[Feb  5 08:15:51] WARNING[4895] mp3/interface.c: Junk at the beginning
of frame 49443303 or
[Feb  5 02:14:05] WARNING[7447]: mp3/interface.c:216 decodeMP3: Junk
at the beginning of frame 49443304

 just before the crash.

I seem to have the same versions.
