Sorry for the delay, I have been on vacation with minimal to no Internet.

All that is a bit confusing to me, but let me try ton understand:
- On a system using dbus-broker, when logged in under GNOME, test fails?
- On *the same system*, but logging-in through SSH works!??

That's worrying, as it suggests the running environment has too much 
influence on the test run, which is not good.

However, IIUC you suggest it might be a dbus/dbus-borken conflict 
somehow?  What if we try `dbus-broker-launch` (assuming it's compatible) 
instead of `dbus-launch` if the former is available?  Would that help?

I don't have any system to test this with yet, and it might take some 
time before I can have a F38 VM up and running with a LO build setup, 
but I'll try and see to this soon if it's a concern.
