Title: cups crashes with SIGABRT every other printing attempt Status in cups package in Ubuntu: New Bug description: Using ubuntu 20.10, cups 2.3.3-3ubuntu1, with a networked Samsung C480 printer (was automatically detected and set up on installation of the system). Every other attempt to print fails with a varying message depending on the printing app (eg. on libreoffice write, "Cannot start printer"). Waiting a few minutes and retrying prints successfully. Looking at cups.service journal messages while attempting to print, it looks like the second printing attempt crashes cupsd cupsd[<pid>]: free(): invalid pointer systemd[1]: cups.service: Main process exited, code=dumped, status=6/ABRT systemd[1]: cups.service: Failed with result core-dump The service then proceeds to restart after a few seconds, and trying to print again succeeds. Trying to print once more thereafter triggers the issue again. Cuspd's error_log shows nothing happening around the crash (it does show some "org.freedesktop.ColorManager.AlreadyExists" error messages on restart, but I figured this would be normal, I can see the same message on other machines that have no printing issues). This is a pretty standard (and recent) ubuntu install, with not much customized; in particular no apport custom config was made, and nothing was configured on cups side or ubuntu print settings, everything is set up as it was autodetected on install. The same printer works flawlessly on a different computer using Arch and cups 2.3.3 as well (albeit without any ubuntu patches, obviously). --- ProblemType: Bug ApportVersion: 2.20.11-0ubuntu50.5 Architecture: amd64 CasperMD5CheckResult: skip CurrentDesktop: ubuntu:GNOME DistroRelease: Ubuntu 20.10 InstallationDate: Installed on 2021-01-28 (12 days ago) InstallationMedia: Ubuntu 20.10 "Groovy Gorilla" - Release amd64 (20201022) KernLog: Lpstat: device for Samsung_C48x_Series_SEC842519933D78_: implicitclass://Samsung_C48x_Series_SEC842519933D78_/ MachineType: ASUSTeK COMPUTER INC.
