Subject: mod_ruby CGI file upload fails because of TypeError ?

hi guys,

i have written an ruby script handling fileupload using the regular
Ruby CGI class.

....
if tmpfile.kind_of?(Tempfile)
        print "creating via FileUtils !!"
        FileUtils.cp tmpfile.local_path.untaint, filename.untaint
        print "i was copied !!"
else
        File.open( filename.untaint, "wb"){ |file|
                file << tmpfile.read
        }
end
....

when executing the script i get the following strange error (copied
from apaches error.log)

/usr/lib/ruby/1.8/delegate.rb:90: warning: already initialized constant
