--- Comment #2 from Austin English austinenglish@gmail.com 2009-02-20 17:08:20 --- I'm not sure this is a wine bug. I've noticed this recently, e.g., when downloading/opening certain file extensions in Firefox (Linux). .bin comes to mind. It attempts to open it in wine, and fails. It may be binfmt-misc that's doing so though...
