So, yeah, that happened. :P
It was my own fault, I was doing something a little 'exploity'.
Found a planet with hallucinatory pollen, walked in straight line along equator of planet for ever, got 26 biodata every time the doctor cured one of the crew.
Profit: 500 creds or so.
Tried it again, ran out of oxygen after spacesuit malfunction(?), everybody died.
I had a 'good improved air filter' so I was getting oxygen even with helmets closed. Maybe the filter broke? Could have been damage from a nearby meteor strike too.
I dunno how smart the AI logic should be - but maybe they could decide to open the face plates themselves before dying? :P
