GLib.GError: g-io-error-quark: Время ожидания истекло (24)

Steps to reproduce the problem

I don't know the steps, I just launch Gajim and get this error repeatedly. The first error had something like g-io-error-quark: Empty reply instead of Время ожидания истекло (24) (translated as "Timeout happened (24)").
