Well, I have to correct myself here: it's not that super-correct
since you are changing 2 factors between 2 tests; you might lead
yourself (and poor unsuspecting developers) into fake conclusion
"it does not happen under gnome", while the it's really "it does
not happen under a newly created user".

Or Xfce4 and Xfce4 and Gnome and Xfce4? (I assume you mean DEs, not
DMs. Or we might as well want to run 2 inits! :D)

Exactly that's what I had in mind.
While I understand that the demand might not be very strong, I do
not really see why multiple sessions could not exist. You can have
as many bashes/zshes/kshes/ashes/cshes as you want, and they don't
start shooting each other in their feet. OK, there's none to very
little overlapping in their spaces, but principle is the same. Why
the hell would Gnome touch Xfce4's files?
What about having one local session and one controlled from a remote
box? What's the principal difference between sshd and *dm?

Yep, that brought up gnome-session with no complaints. (I actually
even omitted the "-- :2" part.) Not via GDM, but that was not
really a requirement, it was rather that I was expecting GDM would
support that. Somehow.

But finally, the benefit was even smaller than as I commented in OP.
While the gnome session seemed to run OK, the actual *application*
I wanted to run didn't. Well, this makes sense in many apps like
MUA or web browser and it is often possible to address by telling
the app to use other profile/dotfileset. But we are just getting
to the point when simply creating user foo is easier.
Thanks all!
