cupsd: Child exited on signal 15! (Invalid cupsd.conf configuration)

Binary package hint: cups

I am running an updated version of Karmic on a Dell Dimension 2300. Result of lsb_release -rd:
Description: Ubuntu karmic (development branch)
Release: 9.10

Version of cups package that is installed:
cups:
  Installed: 1.4.1-2
  Candidate: 1.4.1-2
  Version table:
 *** 1.4.1-2 0
        500 http://nl.archive.ubuntu.com karmic/main Packages
        100 /var/lib/dpkg/status

When I tried to add a printer I noticed that the cups deamon was not running.
When trying to start it (sudo /etc/init.d/cups start) I get the following response:
 * Starting Common Unix Printing System: cupsd
cupsd: Child exited on signal 15!

Searching the forums I learned that when this happened in earlier releases (see for example on UF this thread: http://ubuntuforums.org/showthread.php?t=1009140) that this was caused by an empty /etc/cups/cupsd.conf file.
However, in my case the conf file is present and not empty. Find below the content of the cupsd.conf file:
/dev/sda1 / ext3 rw,errors=remount-ro 0 0
none /proc proc rw 0 0
none /sys sysfs rw,noexec,nosuid,nodev 0 0
udev /dev tmpfs rw,mode=0755 0 0
none /dev/pts devpts rw,noexec,nosuid,gid=5,mode=0620 0 0
none /dev/shm tmpfs rw,nosuid,nodev 0 0
none /var/run tmpfs rw,nosuid,mode=0755 0 0
none /var/lock tmpfs rw,noexec,nosuid,nodev 0 0
none /lib/init/rw tmpfs rw,nosuid,mode=0755 0 0
binfmt_misc /proc/sys/fs/binfmt_misc binfmt_misc rw,noexec,nosuid,nodev 0 0

Please inform me if more information is required.

Just come across this bug with Kubuntu Karmic netbook.

In my case /etc/cups/cupsd.conf was empty, but I haven't noticed it before and /etc/cups/cupsd.conf.O wasn't empty.

That is the contents of /etc/fstab. Why is it in cupsd.conf!? Interesting...

This worked for me:
dereck@yakisoba:~$ sudo cp /etc/cups/cupsd.conf.default /etc/cups/cupsd.conf
dereck@yakisoba:~$ sudo /etc/init.d/cups restart
 * Restarting Common Unix Printing System: cupsd [ OK ]

Dereck Wonnacott's comment got me thinking (and worried that I may have reported something wrong).
As a result of his comment I checked again and the reported content was indeed the content of /etc/cups/cupsd.conf (see attachment).

What I did was:
rdrijsen@dell-thuis:/etc/cups$ sudo cp cupsd.conf.O cupsd.conf
[sudo] password for rdrijsen:
rdrijsen@dell-thuis:/etc/cups$ sudo /etc/init.d/cups start
 * Starting Common Unix Printing System: cupsd [ OK ]

So that resolved the situation.

Question remains ... how did the content of /etc/fstab end up in /etc/cups/cupsd.conf?
