ID 391598 - Crashing/freezing occurs when loading a script while auto-localize is enabled with restricted permissions on a Read node.

Problem summary:
Crashing/freezing occurs when loading a script while auto-localize is enabled with restricted permissions on a Read node.

Customer reported version:
nuke.11.2v5

Customer reported platform:
centos7

Steps to reproduce:

1) From Nuke, open the Preferences... menu. (Edit > Preferences... or Shift+S)

2) Select Localization and ensure it's enabled, also setting an auto-localize path for a networked location.

3) Add a Read node with a networked file from the auto-localized path.

4) View the Read node by pressing 1 on the keyboard to set the Viewer node.

5) Save and close the script.

6) Disable read/write permissions for the ingested Read file from the networked location.

7) Launch Nuke and open the script observing any errors/performance.

8) If Nuke does not crash immediately, double-click the Read node.

Expected behavior:
The script should load with a red bar in the Viewer error stating: permission denied or similar.

Actual behavior:
Nuke crashes when opening the script with a restricted permission Read node and Localization enabled. It has been seen that updating the localization policy on the Read node also makes Nuke unresponsive and crashes the Node Graph; the DAG does not update and the Viewer no longer functions until closing the application.

Workaround:
Turning Localization off or having permissions for the Read file corrects the issue.
