I haven't seen this exact issue, but there was an issue with
secretstorage & jeepney a while back around it actually hanging
because it wasn't properly handling dbus connection problems.  I
reported it against secretstorage but it ended up being an issue in
jeepney. https://github.com/mitya57/secretstorage/issues/22

This bit of code should generally be silently ignored and the backend
should just be ignored if not available so it might be an issue in one
of the dependencies.

Hope that points you in the right direction.

Thanks,
