Steps to reproduce were:
* Append a workspace (via '+' icon) - make sure its from the default workspaces.blend
* Activate it
* Should crash
Was accessing data from view-layer which wasn't updated yet (and thus could be
NULL). Crash occured after rB8153f89518b4a.
@campbellbarton, you may want to check if all object-mode stuff still works as
expected, not sure what's the state of it.
