Can confirm the crash on file load.
Looks like this was saved with multiple objects in editmode.
One of them doesnt have an edit_bmesh though (not sure if this is because it is actually hidden?)

P821 makes the file load (you can also check which object is failing), but I would kindly ask @Campbell Barton (campbellbarton) to take over here...

there was rBcc7460eaa491ed020acdc8f863cd521688fad01c as well (might be related, not sure though...)

Confirmed crash in older version, but appears to work in latest master.
