I can reproduce the problem with:

Does simply adding ‘hicolor-icon-theme’ to ‘inputs’ fix the issue?

Unfortunately, Gajim fails to build for me as described in
<https://dev.gajim.org/gajim/gajim/-/issues/10478>.

Raghav, what should we do about it?  The issue above is closed, but are
we missing the fix?

Thanks,
Ludo’.
