Can you try running gnome-terminal from within mate-terminal or some
other terminal and see if there are any error messages?  You might also
see useful messages in syslog or by running journalctl.

Also, there are some gnome-terminal debugging tips at
https://wiki.gnome.org/Apps/Terminal/Debugging which may help you figure
out what is causing this.
