There's a pango bug that leads to certain programs such as Hexchat and
Termite to crash. It's going around IRC and can be output via

/exec -o python3 -c "print(u'hey \u2665\ufe0e\ufe0f')"

It seems to print "hey" with a heart emoji after it. When viewed from irssi
running in termite, my whole terminal closes instantly. I have irssi
running in tmux, so as soon as I run 'tmux attach', I see the whole window
disappear. I'm able to safely view this text from urxvt, so I can then
/clear my irc window or change to another channel.

Hello!

I can confirm that running the following within Termite crashes the
terminal:

guix environment --ad-hoc python -- python3 -c "print(u'hey \u2665\ufe0e\ufe0f')"

This bug is fixed in pango 1.42.4, which has been "grafted" on the
master branch with commit 7693f678d1de222e47af6b34ce62c41ea69934c8.  I
can no longer reproduce the crash after updating, let me know if you
experience further problems.

Thanks for reporting it!
