ibus-daemon crashed with SIGSEGV in g_dbus_is_name()

[jjunho]

Regularly working with some windows open. No idea what caused the bug.

One possible reason is that I was using LyX (a qt program) and ibus might have crashed because of that.

The system is set for the brazilian portuguese language and I live in Korea, so I have to use Korean and, sometimes, Japanese and Chinese on top of that.
