Created attachment 570796 [details] Backtrace of colord core dump, producing using abrt-cli Description of problem: When attempting to add a CUPS printer, at the stage when /etc/cups/printers.conf should be written, colord dumps core and the printer creation fails. Version-Release number of selected component (if applicable): colord-0.1.15-2.fc16.x86_64 cups-1.5.2-1.fc16.x86_64 cups-libs-1.5.2-1.fc16.x86_64 cups-libs-1.5.2-1.fc16.i686 gutenprint-cups-5.2.7-7.fc16.x86_64 How reproducible: On my Fedora 16 system this is completely reproducible. It happens every time I try to add a CUPS printer, whether using system-config-printer or http://localhost:631 Steps to Reproduce: 1. run system-config-printer as root (to avoid repeated password prompts) 2. click "+Add" to add a printer. 3. pick an auto-detected printer (e.g. USB-connected Epson Stylus Color 740 or a network-connected Samsung SCX-5530FN) 4. pick the recommended driver 5. accept the recommended Printer Name, Description and Location by clicking "Apply". Actual results: A window appears with the message: "CUPS server error: There was an error during the CUPS operation 'server-error-internal-error". CUPS printer is not created (i.e. no entries in /etc/cups/printers.conf). Logs show much activity, including the colord core dump. Expected results: CUPS printer should be created, with an appropriate entry in /etc/cups/printers.conf. Additional info: Some of the keys entries in /var/log/messages are the following: dbus-daemon[1083]: dbus[1083]: [system] Successfully activated service 'org.freedesktop.ColorManager' dbus-daemon[1083]: Cd:ERROR:cd-main.c:206:cd_main_create_profile: assertion failed: (connection != NULL) abrt[5243]: Saved core dump of pid 5240 (/usr/libexec/colord) to /var/spool/abrt/ccpp-2012-03-17-06:29:21-5240 (18341888 bytes) In addition to the colord stack trace, I will be attaching the relevant segment of /var/log/messages I had given the command # cupsctl LogLevel=debug2 before trying to add the printer, and ended up with almost 4MB of output in /var/log/cups/error_log over a one-minute period. I could upload that too, if it might be helpful. After the colord dump occurs (three times), cupsd now dumps core too. I could upload a stack trace of that too, if it would be helpful. Not having any installed printers to print to is a liability for my Fedora 16 system.

A similar problem has proviously been reported for Fedora 15 as bug 705005
This message is a reminder that Fedora 16 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 16. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '16'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 16's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 16 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged to click on "Clone This Bug" and open it against that version of Fedora. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
Fedora 16 changed to end-of-life (EOL) status on 2013-02-12. Fedora 16 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. Thank you for reporting this bug and we are sorry it could not be fixed.
