Bug#958973: ruby-curses: Emits warning: "rb_safe_level will be removed in Ruby 3.0", fixed upstream in 1.3.2

[Axel Beckert]

Package: ruby-curses
Version: 1.2.4-1+b3
Severity: important
Tags: fixed-upstream
Control: affects -1 irqtop

Hi,

running ruby-written irqtop on Debian Unstable contantly emits this
warning:

/usr/bin/irqtop:545: warning: rb_safe_level will be removed in Ruby 3.0

which makes it quite unusable as the curses screen looks like this after
a few seconds:

This has been fixed upstream in the 1.3.2 release, released in December
2019:

https://github.com/ruby/curses/commit/a9b9db9b5d5a4b52e3d0e0eaf0fbb2be839a3c29
https://github.com/ruby/curses/releases/tag/v1.3.2

So please upgrade ruby-curses in Debian Unstable to 1.3.2.

The current version in unstable, 1.2.4 is from September 2017 and there
were 6 new upstream releases since then.

Ruby 3.0 is now the default in Debian Unstable and Testing and due to
this error, irqtop no more works at all there:

Raising the severity to serious accordingly.
