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.

Do you have a reasonable reproducer?
Abrt report is not enough.

Comment 5 Lukas Slebodnik 2017-04-04 07:04:56 UTC

Please provide reasonable steps to reproduce.

Comment 7 Sumit Bose 2017-04-10 12:01:28 UTC

Steeve was so kind to provide me access to one of his test system showing this issue. I think this issues was exposed by https://bugzilla.redhat.com/show_bug.cgi?id=1438374. The backend crashes, the frontend has to setup a new connection which might take some time especially if the backend crashes agan during this time. If then SSSD is shut down the hash might already contain a connection object, although not properly initialized, to avoid multiple initializations.

I prepared a test build with the NULL check before calling dbus_connection_unregister_object_path() and hope that Steeve can confirm that it fixes the issue.
