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.
