Not a huge deal, but I spent a while fighting with various svn errors and finally figured it out.
Unlike distributed VCS, svn relies on clients and a server repo to handle source code. So if a svn 1.3.1 client checks out code the .svn folders are created using that version.
When a 1.6.11 svn client comes a long and tries to do an update from a 1.6.11 server repo the svn client major differences can cause problems.
Such as:
log entry missing 'name' attributesvn: Error processing command 'rm'
