This is due to ​Django Bug. It should be considered during next Django upgrade

This ticket can be closed as Django upgrade should resolve that issue, ​https://code.djangoproject.com/ticket/19664

I'm not sure that this has got anything to do with the "file backend". However, to fix the issue we'd have to handle it in OMERO 4.4, since that's where the problem occurs, and I don't think this is bad enough to justify a 4.4.11.
