System Information
Operating system: Win10
Graphics card: nVidia Quadro 600

Blender Version
Broken: 2.80 3e311fdcd1
Worked: n/a

Short description of error
If you attempt to load a file that was saved during a multi-object editing session, then once re-loaded:

Noticed that only 1 of the objects is still in edit-mode
If you exit edit-mode and attempt to click on the other object that was supposed to be present, you'll get a crash

Exact steps for others to reproduce the error

Load attached .blend
- Basically 2 cubes were created, went into edit mode with both selected, created new geometry, saved file
Hit TAB
Click on the right-most cube in the scene
Crash

rdata->edit_bmesh was nullptr.
