When I launch mate-terminal from a MATE session, it opens and runs successfully. I can also launch uxterm as a Single application (seemless mode.) When I attempt to launch mate-terminal via any of these methods, it segfaults: Single application: mate-terminal Single application: Terminal Single application: uxterm (and then run "mate-terminal") I have attached the relevant lines from /var/log/messages (from the host OS.)
