Comment 17 for bug 1672297

I've installed most of the debug symbol packages, and the attached Massif profile has far fewer unknowns. However, this isn't a proper run, because when I try to log in now, gnome-shell grinds for a minute or so and then quits. Works fine without Valgrind, of course. I suspect it has some form of watchdog timer and is killing itself.
