TestGdkAtom.test_out_glist failed with master running "meson test"

I am updating the gentoo ebuild, initially for own use, and in the ebuild we can automatically run tests. So I decided to run the meson test and got the below. The log: testlog.txt

I ran this in a normal X11 session from an xfce terminal.
