Linux: Crash during shutdown

Noticed this from having my Terminal open.

Repro:

1. Create a Blueprint template project and allow the project to open into the project editor.
2. Shutdown the editor.
3. Observer the terminal output.

Result:
Crash while the editor is shutting down.

Expected:
Editor shuts down cleanly.

Frequency:
100%
