looks to be related altdesktop/python-dbus-next#161

[SFrijters]

Also related: #355880 .
With all the flakiness maybe it's better to try to get consumers to migrate to dbus-fast, which is maintained.

[matdibu]

interestingly enough, it stopped failing on the last ~5 builds
I guess it really is just flaky

[SFrijters]

Should be "fixed" by #360361 .

[matdibu]

thank you!
