From the backtrace, looks like the SDL client is dying while the SDL client is trying to display the following string:

"Раді бачити Вас на сервері Freeciv версія 2.2.4, що запущений на home, порт 5556."

(That's the Ukrainian localisation of "Welcome to the Freeciv version 2.2.4 Server running at home port 5556.", an early opening message.)

Could be some sort of UTF-8 handling failure which only shows up with non-trivial UTF-8 (or maybe only in Ukrainian).

2.2.4 is old; I don't recall any fixes in this area since then off the top of my head, but there may well be some.

Ancient version. reopen if it still affects you.
