[Pkg-xfce-devel] Bug#830517: lightdm: Cannot start sessions after first, requires lighdm restart

Package: lightdm
Version: 1.18.2-1
Severity: normal

Dear Maintainer,

I am encountering difficulties with starting any session beyond the first.
Whether I try to start a second session while the first is still active (that
is, to switch to another user) or after the first user logged out, I get an
error message about DBus not being accessible, and the the (new) session is
ended before anything starts.

If I restart lightdm (from a text console, tty1) then I can log in again, but
again, only once.

FWIW, I'm a KDE/Plasma user; I've had similar and worse issues with sddm, so
the problem may actually be in some other component (systemd?), however, I
currently experience it as a lightdm issue and I don't really know how to
debug it further; I don't see anything which seems related in system logs.
