This caused two issues for us. Using a jQueryFileUpload it would not display a list of existing file and the issue you explained. This only seems to have happened since 16.0.912.63 as I reverted back to an offline version I had downloaded some time back and it did not exhibit the same errors. IE and Firefox are not affected ans seem to handle this.
