[Debian-med-packaging] Bug#1146800: timg: ftbfs with openslide 4.0.1 in experimental

Hi Benjamin, Hi Tobias,

Benjamin Gilbert, on 2026-09-05:

Thanks for your remark, right now I'll stick to focusing on the
transition coordinated in #1146803, so that CVE-2026-54604
finally gets resolved.  In this context, 4f724835ef is mostly a
fix/workaround to avoid jamming the transition on build failure
of timg.

Longer term, I would lean toward my initial idea that pulling
the extra components would be the responsibility of the reverse
dependencies, depending on their build requirements, be it due
to real usage of the headers, or due to constraints caused by
the build management system.  I may be conflating two distinct
issues here, but the situation feels reminescent of #826048
affecting gdcm.  I'm not sure how you would want to move next:

  * the current situation is probably weird but okay for now;
  * I still believe complementing timg build dependencies would
    be appropriate, even if my actions from yesterday don't well
    reflect that;
  * I won't get in the way of complementing libopenslide-dev
    dependencies if you believe this is the right approach, in
    which case I'm okay to tackle a dedicated bug or apply a
    patch.

What do you gentlemen think?

Have a nice Sunday,  :)
