I am not clear regarding what to search for, so let me reason at loud.
The following command allows me to find the corresponding derivation:
$ find /gnu/store -name '*.drv' -exec grep 5x9zxdmxphmprlchfl3a2y8w5ykcwkjc
{} +
→ /gnu/store/xhg66izrd1ijnaqzk8zxrfn6i5lwgqdi-glibc-2.25.drv
Next to see what packages refers to this derivation I run this:
$ guix gc --referrers
/gnu/store/xhg66izrd1ijnaqzk8zxrfn6i5lwgqdi-glibc-2.25.drv
→ /gnu/store/1msbfj9jljqm3zj17fwq0gqzw4vww7h8-glibc-2.25.drv
This corresponds to 38kr8xi7nib8rx8xr4gi0w0d8knyca3k-glibc-2.25 found in
the following “bad” strace log:
--8<---------------cut here---------------start------------->8---
30147
open("/gnu/store/38kr8xi7nib8rx8xr4gi0w0d8knyca3k-glibc-2.25/lib/gconv/gconv-modules.cache",
O_RDONLY) = -1 ENOENT (No such file or directory)
30147
open("/gnu/store/5x9zxdmxphmprlchfl3a2y8w5ykcwkjc-glibc-2.25/lib/gconv/gconv-modules",
O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory)
--8<---------------cut here---------------end--------------->8---
IIUC 38kr8 is a grafted version of 5x9zx. So what seems to happen is
that there is “something” found in “$HOME/.guix-profile/lib” by the
dynamic loader that contains a reference to '5x9zx' but should be
grafted to refer to '38kr8'. Is that correct?
So the faulty package should be in the outputs corresponding to the
following list:
$ guix gc --referrers
/gnu/store/1msbfj9jljqm3zj17fwq0gqzw4vww7h8-glibc-2.25.drv
/gnu/store/2mf7rkp0gs61gffip9k3vzxrqdin2nqw-xdg-mime-database.drv
/gnu/store/64xh3mr0l597j2dwqsaw4y72563mg2n2-gtk-icon-themes.drv

/gnu/store/h0khj5wnfskjrw9r3cmp6rsk5ncj29ws-info-dir.drv
/gnu/store/jamz10xa4hbglbqc49iyj3wp6fm7sq3b-gtk-im-modules.drv
/gnu/store/lx64j3l2j53sav1gzi2flylm0lp5kvym-profile.drv

/gnu/store/s01vvhbb2hz76fsch1js5g0p50vbk9y5-xdg-mime-database.drv
/gnu/store/wdzl6xdrdvy196ia9n0mj7f5v5fiyl2r-xdg-desktop-database.drv
Would it possible to grep in the corresponding outputs? For now I have
run tried in my profile without success:
$ grep -RU 5x9zxdmxphmprlchfl3a2y8w5ykcwkjc-glibc-2.25 $HOME/.guix-profile

What would be your methodology?
