wget-1.9.1-5 (fedora core 2) When downloading something to a specific filename with -O, wget gets confused when running convert-links and tries to access the filename as if -O wasn't specified, returning a "file not found" message.
Also, I'm guessing that this won't work at all with -O /dev/stdout, so I would request/suggest that --convert-links happen as a preprocessor, before/during printing of the file. -Chrir
