Maybe I miss something and I have not dove into all the details so I
could be totally wrong. However, from my understanding, A is built
against the shared library C1, and B is built against the shared library
C2, and nothing says that C1 and C2 are compatible. If you run A inside
B, then C2 is used for both A and B, and A fails because it expects C1
and finds instead C2. I miss why it is considered as a bug. Aside the
fact that A and C1 are system-wide so without any control on how it is
built.
>From my understanding, it is a bug if A built against C2 run inside B
built too against C2 does not work; which correspond to:
guix environment --pure --ad-hoc emacs evince
emacs -q -f shell
and type “evince”.
Then I do not have any error when I open the print dialog; but I have no
setup for CUPS on my machine though.
And it appears to me also a bug if:
guix environment --pure --ad-hoc emacs-no-x
emacs -q -f shell
and type “/usr/bin/evince” where the print dialog fails. On my machine,
it is not the case; but I have no setup for CUPS on my machine though.
Otherwise, from my point of view, failure should happen and I miss why
it should be considered as a bug, but as I said, I should probably miss
something and be wrong.

On foreign distro or Guix System?
All the best,
