Comment 2 for bug 485059

Same here on 9.10, I tried all kind of different things including pinning CUPS and related dependencies from lucid, it always lead to the same segmentation fault.

The only workaround that I found, to be able to use the printer again, was to blindly add a printer from the CUPS admin page and point it to "parallel:/dev/usb/lp0" (and then use the right PPD file, etc) as explained here: https://bugs.launchpad.net/ubuntu/+source/cups/+bug/436495
