Engine version

My Operating System

Linux localhost.localdomain 4.17.3-200.fc28.x86_64 #1 SMP Tue Jun 26 14:17:07 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux

Can you describe how to trigger the error? (eg: what sequence of actions will recreate it?)

Was testing something unrelated. Not sure what I did at the time to trigger this. All I was doing was moving and scaling the map window.

Do you have the exact error text? Please copy/paste if so

Instead of this error, what should have happened?

NPE should not occur.
