Emacs crashes after triggering an X error message.

To reproduce the error, I have to start emacs as a daemon via

> emacs --fg-daemon

and a client via

> emacsclient -create-frame --alternate-editor=""

As soon as I open a source file (C++ in my case), emacs crashes
immediately based on the following X error:

X protocol error: BadLength (poly request too large or internal Xlib
length error) on protocol request 139
When compiled with GTK, Emacs cannot recover from X disconnects.
This is a GTK bug: https://gitlab.gnome.org/GNOME/gtk/issues/221
For details, see etc/PROBLEMS.
Fatal error 6: Aborted

This does *not* happen when I launch emacs directly.

Note: the bug seems to be very similar to the
one reported here:

https://debbugs.gnu.org/cgi/bugreport.cgi?bug=30874#33

My emacs is (naturally) heavily modded, and I was not able to pinpoint
the problem to one concrete package. Noticably, I *can* enter the
unicode symbol 274c.

I suspect that the theme I am using (doom) triggers the rendering of
some unicode glyph or icon causing the error.
