fdns --proxies: Segmentation fault (core dumped) if /run/fdns is not present

[rusty-snake]

STR:

• If any fdns instances are running: stop them and delete /run/fdns (and maybe /dev/shm/fdns-* too).
• Run fdns --proxies
• See

  pid fb,
  Segmentation fault (core dumped)

• Create /run/fdns (sudo mkdir /run/fdns)
• Run fdns --proxies again
• See blank line -- no segfault
