The patch being uploaded contains several modified files, 1 properties files that is moved and 2 java files that are being moved. The moved files appear as a delete and then create in the svn diff. It is only the 2 java files that are being deleted that has the problem.
The java files are configured with "svn:eol-style=native;", but the working property file is not. The property file has "\ No newline at end of file" at the end of the diff in the patch, but the java files do not.
Let me know if there is a way of uploading private attachments and I will send you the contents of the /tmp/reviewboard.3wU_dl folder.
