I could reproduce this (relevant part below). *But*, it passes when I try run it locally with

(i) "bash ./debian/tests/run-unit-tests" --> OK

and also, inside a container with -- null

(ii) "sudo autopkgtest -B ../*.deb -- null" --> Works perfect.

It does not work when I try running it in a schroot, or an lxc container and gives errors similar to the one quoted below.
I tried changing locales with several different permutations, but the result is same.

Since this does not really look like a bug with this package, but rather something very specific to "autopkgtest" or "schroot" environment is triggering this,
I need your inputs to tackle this.

Would you have any idea as to what autopkgtest might do differently in a chroot? Or what is specific there to be causing this?

I'd really appreciate any pointers.
