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.

Comment 4 Ahmad Samir 2020-09-01 10:33:48 UTC 
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.
Comment 5 Don Curtis 2020-09-01 11:19:55 UTC 
(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).
Comment 6 Ahmad Samir 2020-09-10 09:56:13 UTC 
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
