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.

Description Michal Odehnal 2019-12-02 09:35:13 UTC 
This bug has been created based on an anonymous crash report requested by the package maintainer.

Report URL: http://faf.lab.eng.brq.redhat.com/faf/reports/bthash/2ac0efe4c6cbc444af5f7e51d3b775b68cc93a4e/
Comment 5 Thomas Haller 2019-12-03 14:01:03 UTC 
libnm got heavily reworked in 1.22.0 release (which appears in rhel-8.2 as "1.22.0-0.2.el8"). So, this crash is possibly related.


I changed this in libnm, to no longer emit a signal [1]. It will be fixed soon in rhel-8.2.

However, I think this is a bug in g-c-e: it must disconnect from all signals before it gives up the last reference to NMClient (or use g_signal_connect_object()). Hence: reassigning back.


(Also, if somebody can reproduce this, it would be good to have a stack trace with debug info installed. On the other hand, comment 3 seems to indicate that the reasons are well understood, so, never mind...).

Fair enough, that seems to be what happens upstream already.

I have a fix ready for this, just the right flags are missing.
Comment 8 Carlos Garnacho 2019-12-04 13:06:16 UTC 
There's a fix in 3.28.2-9.
Comment 11 Michal Odehnal 2019-12-05 09:51:19 UTC 
Gating tests passed with no apparent fail nor a FAF report. Tests started by hand passed without any issues. Switching to VERIFIED.
