Thanks for explaining, I understand better now.

I think that it’s not satisfying to apply a workaround that we don’t
understand.  That is, intuitively, I see now reason why propagating
libkscreen would “fix” a segfault.

Could you either (1) provide an ‘operating-system’ config and
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’.
