[DRE-maint] Bug#996515: ruby-tilt: FTBFS with ruby3.0: ERROR: Test "ruby3.0" failed: TypeError: no implicit conversion of Hash into String

[Antonio Terceiro]

Source: ruby-tilt
Version: 2.0.10-1
Severity: serious
Justification: FTBFS
Tags: bookworm sid ftbfs
User: debian-ruby at lists.debian.org
Usertags: ruby3.0

Hi,

We are about to enable building against ruby3.0 on unstable. During a test
rebuild, ruby-tilt was found to fail to build in that situation.

To reproduce this locally, you need to install ruby-all-dev from experimental
on an unstable system or build chroot.

Relevant part (hopefully):
