We upgraded to Mac OS X 10.5.3 and getting problem when uploading files (PUT) to a webdav server (the server is Apache running on a Windows environment). When we drag and drop on to a webdav folder using Finder we get a -36 error. When looking at the stack trace of the web server the problem is due to INVALID CRLF or some times getting the following error. Both the stack point to error when copying the stream. When googled found that it is because the Mac changed to Transfer-Encoding to 'Chunked'
