This is a crash in the D-BUS backend. Unfortunately the stack trace is only for the client side, but that's quite worthless. Can you please open a terminal, run
sudo /usr/lib/language-selector/ls-dbus-backend --debug then use language-selector and reproduce the steps that lead to this crash? (Looks like you were trying to set new language/region system- wide). That should crash ls-dbus-backend, and you should get some output. Can you please copy&paste that here?
