Thanks for this bug report.
If you can, please share the server-side stack trace in your PHP error log (its location depends by your webserver).

Hello boz,
This issue occurred in our production environment. However, I have since left the company and am unable to provide any further information. I will proceed to close this issue.
Thank you, boz.
