I have recovered SVN repository from crashed PC and now I can checkout files from few directories but in one place during checkout it says:
Error: REPORT of \'/s
I had similar issues, for which 'svnadmin recover' did indeed magically fix things.
On another repo, it would not... Using the Versions SVN client (MacOSX) I could see that the commit user name of some files in misbehaving directories was '###ERROR###' - these dirs were giving me the "Secure connection truncated" issue on update. Simply 'moving' the files that had this marker into another directory and back (on the server, via the Versions SVN client), was enough to remove the ###ERROR### marker and enable successful update.
