I've upgraded dapper to edgy and have been getting that message on .wav, .ogg, .png, .jpg, but not on .gif or .jpeg. Mine says it like this:
The filename "PNG_transparency_demonstration_1.png" indicates that this file is of type "png document". The contents of the file indicate that the file is of type "PNG image". If you open this file, the file might present a security risk to your system... I note that it says it is type png document rather than png image. -- nautilus's clever anti-hax0r detection is really dumb https://launchpad.net/bugs/19101 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
