Ardour crashing again, now won't load new or old session

Ardour is crashing an startup, both with saved sessions and with newly created ones. The error message is:

(ardour-2.8.11:6298): Gtk-WARNING **: EnableTranslation: missing action EnableTranslation
Session writable based on /home/gene/Ardour/The Door/
Segmentation fault (core dumped)

Forums don’t work for this sort of thing. My first guess is zoom level, but there’s no way to check on that without lots more detail and the forum is the wrong place for that.
