[Debian-astro-maintainers] Bug#1071703: gammapy: test fail with scipy 1.12

[Drew Parsons]

Source: gammapy
Version: 1.1-4
Severity: normal

gammpy appears to be using a deprecated RootResults API that fails
with scipy 1.12

This bug will become serious when scipy 1.12 is uploaded to unstable
in the near future.
