It seems like files with the '@' character in the name cannot be added to a repo. I've verified this in two different repos using SVN version 1.6.17.
Here are the repro steps: nick@nimble ~/test_repo $ svn --version svn, version 1.6.17 (r1128011) compiled Feb 26 2012, 12:28:33 nick@nimble ~/test_repo $ svn status nick@nimble ~/test_repo $ ls nick@nimble ~/test_repo $ touch "test@foo" nick@nimble ~/test_repo $ ls test@foo nick@nimble ~/test_repo $ svn add ./test\@foo svn: warning: 'test' not found nick@nimble ~/test_repo $ svn add "test@foo" svn: warning: 'test' not found Is this a bug? Best regards, Nick
