Ouch, it might be the same issue. I don't have gnome-shell installed, and installing the metapackage didn't enable a session in lightdm. The "Ubuntu" (Unity) shell prouces the same crash. But "sudo pitivi" works fine.
I'll look around to enable a gnome-shell session and try from there. Thanks for the suggestion, Lubosz!
