Note: the files themselves are not "damaged" -- Subversion will never alter the contents of a file when it is first imported/added. It may make a file look different in the working copy, according to svn:eol-style. But the svn:mime-type is just a property associated with the file. Its only real use is when the file is served via HTTP to a web browser. If a file is committed to the repository with an svn:mime-type, why don't you just delete/correct the property in a following commit? Cheers, -g
