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.

nm_keyfile_connection_get_path (data) returns NULL here:

347		g_hash_table_iter_init (&iter, priv->connections);
348		while (g_hash_table_iter_next (&iter, NULL, &data))
349			g_hash_table_insert (oldconns, g_strdup (nm_keyfile_connection_get_path (data)), data);

This is with NetworkManager-0.9.9.0-24.git20131108.el7.x86_64.
Comment 2 Jirka Klimes 2013-11-20 15:08:23 UTC 
Already fixed in upstream master:
http://cgit.freedesktop.org/NetworkManager/NetworkManager/commit/?id=07bf4eb802166edc737f2c742f3987a1aa39189e

The fix will propagate to a RHEL7 build soon (with the next update).
