Get this message when attempting to commit either through svn command line (1.8.0) or TortoiseSVN 1.8.0. This is a working set that was upgraded from svn 1.7, and the server is a hosted svn on atlassian.net which is Subversion version 1.6.11 (r934486). Others are having the same problem here: https://groups.google.com/forum/#!topic/tortoisesvn/o5taYV-bm0c
Thanks, Josh
