Bug#1121244: trixie-pu: package qiv/3.0.1-2+deb13u1

[Bart Martens <bartm@debian.org>]

Package: release.debian.org
Severity: normal

Can qiv 3.0.1-2+deb13u1 be added in trixie-updates?
qiv 3.0.1-2 in trixie always produces a 'segmentation fault'. qiv
3.0.1-2+deb13u1 includes the smallest possible fix. The fix is
cherry-picked from a newer upstream release of qiv.

[ Reason ]
qiv 3.0.1-2 in trixie always produces a 'segmentation fault'.

[ Impact ]
qiv 3.0.1-2 in trixie is unusable most users. Only users who find their
way to the workaround on #1103712 know how to make the package usable.

[ Tests ]
Switching between 3.0.1-2 and 3.0.1-2+deb13u1 makes the problem appear
and go away 100% of the times. Tested on a fresh trixie setup.

[ Risks ]
In my view the risk is low. It is an extremely small code change.

[ Checklist ]
  [x] *all* changes are documented in the d/changelog
  [x] I reviewed all changes and I approve them
  [x] attach debdiff against the package in (old)stable
  [x] the issue is verified as fixed in unstable

[ Changes ]
Added patch debian/patches/putenv-x11.diff is cherry-picked from
upstream. It adds 'putenv("GDK_BACKEND=x11");' to the source code.
Upstream's explantion is "set GDK backend to x11. Otherwise qiv won't
work on wayland.". This matches the reported problem on #1103712.
