Comment 40 for bug 271677

I'm still doesn't see any fixes for this problem.

 if [ "`file --brief --mime \"$ISO_IMAGE\" | grep \"application/x-iso9660\" | wc -l`" = "0" ] ; then
  dialog_msgbox "Not an ISO image" "File $ISO_IMAGE does not seem to be a valid ISO9660 image"
  continue
 fi

But the Iso's on my system appears as:

file --brief --mime ubuntu-9.10-desktop-i386.iso
application/octet-stream; charset=binary

Checksum of the iso is correct! But also my old hardy iso's are shown as "application/octet-stream; charset=binary"! Maybe it's an bug in "file"!?
