Crash when accessing location on CIFS mount permission denied

[aprayez]

Version: Gaffer 0.53.3.0-linux
Third-party tools: None
Third-party modules: None

Description

As far as I can tell, every time I try to open a location for which I don't have the read rights, that's on a cifs mount, gaffer crashes.

Steps to Reproduce

1. Create a folder NO_READ/ anywhere on your CIFS file server
2. Remove all access for userA on location NO_READ/
3. As userA mount the CIFS location onto something like /mnt/projects
4. Launch gaffer, create a SceneReader, navigate to /mnt/projects/..../NO_READ
5. Crash ?
