The backslashes were caused by a bug in cups-browsed (package cups- filters) which I have already fixed before release of 16.10. So after once removing these entries manually, they should not show up again and show the crash should not occur again.
But in general, CUPS has no sufficien protection against too long info/description strings. This should get reported as upstream bug on http://www.cups.org/. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to cups in Ubuntu. https://bugs.launchpad.net/bugs/1635856 Title: cupsd 2.2.0-2 crashed with SIGABRT in __malloc_assert() Status in cups package in Ubuntu: New Bug description: I am unable to print after a smooth upgrade from 16.04 to 16.10, as the cupsd service would not start.
