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.

Comment 13 Milan Crha 2014-06-03 07:52:35 UTC 
The backtrace seems to show some ref/unref imbalance on a CamelFolder/CamelStore, but there is no indication what exactly happened. It is only some async operation end when the bug stroke.

I managed to reproduce this, even not fully reliably. Nonetheless, I see the cause. The problem is that a CamelFolder delivers its change notifications on idle, but its store can be freed before the idle happens, because it is freed together with a temporary CamelSession in shell/e-convert-local-mail.c:324. Making sure that all what is piled is also delivered during the lifetime of the temporary CamelSession makes this work properly (no use-after-free).
Comment 15 Milan Crha 2014-06-10 12:55:44 UTC 
I forgot to add, my most often reproducer was to restore from a backup, but uncheck [ ] Start Evolution after restore, rather run evolution on my own from a terminal (with simple `evolution`). the issue exhibited like once per 5 starts. 

I can provide a test build with a debug prints which can show whether the event occurred or not, if you want.
Comment 17 Jiri Koten 2014-12-04 10:23:58 UTC 
Evolution still crashes after the dialog of Migration from mbox to Maildir. Backtrace looks different - see bug 1170552
Reproducer is the same.
Comment 18 Milan Crha 2014-12-05 06:01:36 UTC 
Let's deal with it there, it looks like a different issue to me too. Weird it didn't strike earlier. I would guess a change in sqlite3, but that didn't change for you. I will eventually mark that as a duplicate of this, if further investigation will prove so.
