RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

    fn ()
File "/usr/share/system-config-printer/probe_printer.py", line 322, in _probe_hplip
    stderr=null)
File "/usr/lib64/python2.6/subprocess.py", line 639, in __init__
    errread, errwrite)
File "/usr/lib64/python2.6/subprocess.py", line 1220, in _execute_child
    raise child_exception
OSError: [Errno 2] No such file or directory
Continuing anyway..
params.c:OpenConfFile() - Unable to open configuration file "/root/.smb/smb.conf":
    No such file or directory
params.c:OpenConfFile() - Unable to open configuration file "/root/.smb/smb.conf.append":
    No such file or directory

no traceback and its able to find some printers (if available)
Comment 1 Tim Waugh 2011-06-20 13:39:55 UTC 
The traceback is non-fatal and only printed to stderr for information:
