I have also experienced this problem under Lucid where: xdg-mime query filetype /bin/true
does not output any information. I tried: XDG_UTILS_DEBUG_LEVEL=1 xdg-mime query filetype /bin/true and did get a message Running gnomevfs-info "/bin/true" However, gnomevfs-info is not available on my PATH. The package libgnomevfs2-bin contains the /usr/bin/gnomevfs-info file, but this package was not installed. After installing libgnomevfs2-bin: xdg-mime query filetype /bin/true displays application/octet-stream The xdg-utils package lists libgnomevfs2-bin as a suggested package. -- xdg-mime query filetype FILE: no output at all https://bugs.launchpad.net/bugs/602799 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
