[Santiago Vila]

Package: src:ruby-sprockets-rails
Version: 3.4.1-2
Severity: serious

Dear maintainer:

During a rebuild of all packages in bookworm, your package failed to build:

--------------------------------------------------------------------------------

(The above is just how the build ends and not necessarily the most relevant part)

Note: I'm using the "patch" tag because there is an obvious fix
(indicated in the subject).

About the archive rebuild: The build was made using virtual machines
from Hetzner, with enough memory, enough disk, and either one or two
CPUs, using a reduced chroot with only build-essential packages (plus
debhelper).

If you could not reproduce the bug please contact me privately, as I
am willing to provide ssh access to a virtual machine where the bug is
fully reproducible.

If this is really a bug in one of the build-depends, please use
reassign and affects, so that this is still visible in the BTS web
page for this package.

Thanks.
