> So the problem here is it's too late to be doing setenv; we've already initialized threads. Some other thread could call getenv at the same time -- there are getenv calls in many many places -- and crash. It's not a theoretical issue, I've seen multiple cases of this crashing gnome-session.

It's not that I want to se the display here, DISPLAY has already been set, but g_test_dbus_up() unsets it unconditionally, so I'm just restoring it because otherwise nothing works (the web process needs DISPLAY to be set to work). This has nothing to do with gnome-session, this only affects the tests.
