From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.5) Gecko/20041107 Firefox/1.0 Description of problem: When starting cups, either during boot or manually, I get: /etc/rc.d/init.d>./cups start Starting cups: Traceback (most recent call last): File "/usr/sbin/printconf-backend", line 7, in ? import backend File "/usr/share/printconf/util/backend.py", line 54, in ? which = cups_import.which_spooler () File "/usr/share/printconf/util/cups_import.py", line 191, in which_spooler which = l.split ('.')[1].strip () IndexError: list index out of range Version-Release number of selected component (if applicable): system-config-printer-0.6.116.1.4-1 How reproducible: Always Steps to Reproduce: 1.Install the driver that comes with the Samsung ML-1520 laserprinter 2./etc/rc.d/init.d/cups start 3. Actual Results: See error in 'Description' Expected Results: No phyton 'trace' should be printed. Additional info: The reason for this is because there is no '.' in the investigated output at that point. In fact, in my case I have: /etc/rc.d/init.d>LANG=C /usr/sbin/alternatives --display print | head -n 2 print - status is auto. link currently points to /usr/local/linuxprinter/bin/llpr Where "/usr/local/linuxprinter/bin/llpr" is part of the "Linux Printer Package", a driver that came with the Samsung ML-1520 laser printer (they support linux). Since the result of which_spooler is only used to test whether or not the CUPS queues need to be imported, I think that a better, more generally robust, test can be easily performed. Not one that assumes a '.'. For example, you could return 'Other' when there is no '.'.
