Segfaults on connection loss

[zorun]

Hi,

I got a new Tinc segfault, again in a condition of bad network connectivity:

  Old connection_t for mejis (XX.XX.XX.XX port 656) status 0010 still lingering, deleting...
  Segmentation fault (core dumped)


This is tinc version 1.0.24 on Archlinux x86_64:

  # tincd --version
  tinc version 1.0.24 (built May 12 2014 09:24:12, protocol 17)


I have a core dump, but I doubt it's very useful, as it doesn't have
any debug symbols.
