LDAP error on discard can hose UI

I noticed that if you setup an LDAP user but discard a change, you will see the attached error. If you subsequently logout (other actions may trigger this), you'll see a garbled logout message and be missing headers then subsequently a garbled login on retry - the UI appears totally hosed tho is partially navigatable. You'll need to refresh the browser to get the UI restored.

This issue occurs with debug on or off. With debug on you also see the below in the browser console. Nothing shows in the nexus.log.
This does not occur with a non-LDAP (nexus "default") user.
It occurs on initial setup or on later edit.

I did not check older (pre-m7) NX3 or NX2 at this time.

Let me know if you desire a video.
