Leads to fcitx5 crash when trying on using it on xdroid (Anbox-like app)

[1]+  Speicherzugriffsfehler  (Speicherabzug geschrieben) LANG=C fcitx5

Other things in fcitx5 work, input methods and QuickPhrase so the problem is most likel really somewhere in the im-emoji-picker engine. The engine works in all other apps I tried so far. I'm on X11, Arch Linux x86_64.
