Control: severity -1 important Since gtkmm4.0 is new to Debian, a broken autopkgtest isn't a regression and doesn't block migration to Testing.
I've fixed the one line seen in the autopkgtest failure, but… We need to either port the minimal gtkmm app to gtkmm4 or drop it and just use the included demos apps to test whether simple gtkmm apps build and work. Thank you, Jeremy Bicha
