To me it seems to only be happening with Lubuntu session, not with LXDE.
I mean:
With installed lubuntu-core package:
lxsession -s Lubuntu -e LXDE # has described bug
With installed lxde package:
lxsession -s LXDE -e LXDE # does not have described behavior
By "does not have described behavior" I mean the sessions starts up without any messages.
I run this stuff in lxc container with trusty on both host/guest.
