Comment 12 for bug 1800040

GDB installed and it's now showing some more info.
Config:
  Selene (Bacula host) has just been upgraded to Disco, Bacula now version 9.4.2.
  Bat running from Selene via ssh tunnel (ssh -X userxxx@selene)
  Client -> Status Client causes FD to fail, Bat still reports new version of client and sometimes gets some data in header tab.
