Note: This bug is displayed in read-only format because
the product is no longer active in Red Hat Bugzilla.
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.

Reproducer is kind of tricky:
1. I have removed panel on left monitor and added "default panel" -> it worked
2. then I did same on right monitor -> it crashed
3. then I added and removed panel several times on right monitor -> no crash
4. I removed/added panel back on left monitor -> crash
TL;DR: so, every time I move to another monitor and do the steps, it crashes for first time. (except the very First time)

I'm not able to reproduce it on machine with RHEL 7 and even on Fedora 20. Martin says he is not able to reproduce it with a new user, so I suspect some weird configuration, which got broken during various testing.
I'm going to close this bug. I was not able to reproduce it and I believe that Martin had this problem because of his shared /home directory between multiple instances of RHEL and Fedora.
