Harri,

This is addressed in bug 8363 (http://trac.openmicroscopy.org.uk/ome/ticket/8363) and fixed in PR320 (https://github.com/openmicroscopy/openmicroscopy/pull/320).  Basically it's an artifact when running nginx as the omero user vs as the general OS user.

Comment (or remove) out the fastcgi_temp_path and proxy_temp_path directives from your omero-nginx conf file and this issue will go away.  Omero doesn't make use of the nginx_tmp directory directly and nginx has no need for it to be located within the omero install when it's running as the OS defined user.
