Thanks for explaining, I understand better now.

I think that it=E2=80=99s not satisfying to apply a workaround that we don=
=E2=80=99t
understand.  That is, intuitively, I see now reason why propagating
libkscreen would =E2=80=9Cfix=E2=80=9D a segfault.

Could you either (1) provide an =E2=80=98operating-system=E2=80=99 config a=
nd
instructions to reproduce the problem, or (2) grab a backtrace of the
segfaulted program with GDB?

Let us know if you need guidance.

Thanks,
Ludo=E2=80=99.
