Error "ObjectLockContext has not been set." on Properties of Apps, Deployment Types, Task Sequences etc.

Using a specific AD account, when I attempt to view the properties of any Applications, any Deployment Types, any Task Sequences or edit any Task Sequences, I see errors similar to below.

Appears to be specific to that account as my own works fine.

Thoughts on what might be happening?
