Bug#1099694: papers: fails to build

[Jeremy Bícha]

Source: papers
Version: 48~beta-3
Severity: serious
Tags: ftbfs trixie sid
X-Debbugs-CC: debian-rust at lists.debian.org

Papers now fails to build. Because the build succeeds in Ubuntu 25.04
which is generally very similar to Debian Unstable currently for GNOME
and Rust dependencies, my guess is this might be caused by rustc 1.85.
Ubuntu 25.04 uses rustc 1.84 instead.

Papers 48 RC also fails to build in Debian.

The full build log can be found in recent Salsa CI pipelines.
