Bash 3 in xterm, running ctorrent as normal user.

>Description:

I downloaded the FreeSBIE 1.1 torrent metainfo file from ...

  http://torrent.freesbie.org/FreeSBIE-1.1-i386.torrent


... ctorrent then downloaded the folder; no problems so far.

Later running ctorrent w/ the same torrent metainfo file, it crashes
resulting in 3.9 MB core dump w/ segmentation fault; backtrace is
below ...

  warning: exec file is newer than core file.
  Core was generated by `ctorrent'.
  Program terminated with signal 11, Segmentation fault.
