Emacs 27.1 crashes on input method selection

[Zelphir Kaltstahl]

Hi Guix users!

I installed Emacs 27.1. via GNU Guix and I found one action, which
always crashes Emacs in this version, while it did not do that before:

M-x set-input-method RET chinese-py RET

It crashes completely and shows no error, simply goes down. Am I the
only one? Does it happen for anyone else? I am assuming, that this only
happens with the GNU Guix installed version of Emacs, but have not
tested that.

My system is a Trisquel 8 on an X200.

What more info could I provide and how, to find the cause?
