akonadi_archivemail_agent (5.14.2 (20.04.2)) using Qt 5.12.7
- What I was doing when the application crashed:
Adding a MailDir to be archived - entered the parameters and saved them, left the automatic Archive setup and waited a minute or so.
* The crash occurred when the newly configured automatic Archive began running for the first time.

The backtraces are not all the identical, e.g. the one in the original post and the one in comment#2, are missing some debug symbols: 0x000055aa430c6170 in ?? () the backtraces from comment#1 and #3 are slightly different. (In reply to Ahmad Samir from comment #4) > The backtraces are not all the identical, Hardly surprising: * The first Segmentation Fault occurred when adding the first periodic Archive. * The second when the second periodic Archive. * The third when an automatic Archive began running for the first time. * The fourth when I took a look at the settings. ------------------------------------------------------------ A segmentation fault or access violation is a fault, or failure condition, raised by hardware with memory protection, notifying an operating system (OS) that, the software has attempted to access a restricted area of memory (a memory access violation). What I found out so far, the stack trace in comment #1 is a different issue than the other ones, that one is caused by deleting mInfo in the ArchiveJob dtor, it looks like a race issue caused by that objected (allocated with new) having already been deleted in the dtor of ArchiveMailManager, I think this can be fixed by using shared_ptr to manage ArchiveMailInfo objects which are passed from ArchiveMailManager too ArchiveJob. The other stacktraces, are a crash in QObject::metaObject(); proxiesAndModel from EntityTreeModel, calls qobject_cast which calls QMetaObject::cast: const QObject *QMetaObject::cast(const QObject *obj) const { return (obj && obj->metaObject()->inherits(this)) ? obj : nullptr; } the crash happens in obj->metaObject(), I haven't been able to figure out why exactly that happens. Steps to reproduce that crash: - KMail -> Settings -> Configure automatic archiving - Attach gdb to the running akonadi_archivemail_agent - Create a new archiving job, OK/Apply - Wait a while for the scheduled job to fire - Crash Git commit 0922a95a692f6424773cd28f21a83237a60d226f by Laurent Montel.
