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
