Event Timeline

Philipp Oeser (lichtwerk) lowered the priority of this task from Needs Triage by Developer to Confirmed, Medium.

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.
