Public bug reported:

Binary package hint: cupsys

error.log:
[] PID 13288 (/usr/lib/cups/cgi-bin/printers.cgi) crashed on signal 9!
and cups crashes (stops).
After 
 /etc/init.d/cupsys start
cups tries to print the file again and crashes again.

affected versions: 1.2.4 (edgy) and 1.2.8 (feisty)
not affected: 1.2.0 and 1.2.2 (dapper)

Even this bug is provoked by a 3rd-party-driver, it's cupsys to blame:
3rd-parties should not be able to rise signal 9.

Steps to reproduce:
1. Download the _rpm_ version of the Brother lpr and cupswrapper driver.
http://solutions.brother.com/linux/sol/printer/linux/lpr_drivers.html
http://solutions.brother.com/linux/sol/printer/linux/cups_drivers.html
2. convert them with alien (don't use --scripts)
3. 
 ln -s /etc/init.d/cupsys /etc/init.d/cups
 ln -s /etc/init.d/cupsys /etc/init.d/lpd
3. install the generated debs
4. install the attached tar-file with the ppd and cups-filter
5. /etc/init.d/cupsys restart
6. Set up a bsd lpd:// printer queue 
    for Manufacturer:Brother
    printer: MFC-5840CN (handmade) or MFC-5840CN (hes)  or something similar 
(can't remember exactly).
7. Send printer test page.

If you have a bsd lpd running, you can downgrade to cupsys 1.2.2 to get
a running version, which breaks again at upgrading to 1.2.4 or 1.2.8.
