When the system is booted, the mountall process may notice a temporarily-mounted file system at /var/lib/ureadahead/debugfs and record that fact in /etc/mtab. Later in the boot process, this file system is unmounted, but mountall doesn't record unmounts, so it never "forgets" this path when it's unmounted.
Mountall should if necessary remove this mount from mtab.
To confirm on your system that it is indeed not really mounted, look for it in /proc/self/mountinfo
Otherwise this may be due to a crash of the ureadahead process during boot.
