A fresh start with KMail

Peter Humphrey-3
Hello list,

Having tired (many times :) ) of wrestling with KMail, I've decided to start
again from scratch. Not only a new user account, but no import of old emails.
I've created the folder structure and imported my filters, but I've no emails.
This one may even be the first.

My reasoning is that something must be wrong with the store of emails I've
built up over the years, to cause such mayhem. So: save it somewhere safe and
start all over again.

Well, I know it's early days yet, but after receiving 50 emails via POP3,
kmail is behaving itself impeccably. This reinforces what I said:

So now it seems there's an opportunity (!) to ferret out where kmail is
vulnerable to its own data structures. Perhaps something as simple as wrongly
specified array bounds. As I said before, though, I'm not confident I could
help in that search, though I'd be happy to give it a go if I had a pointer to
where to start.

I'd open a bug report if your KDEPIM version is recent enough and
provide as much data as I could. But only if it is recent enough. I do
not open any new KDEPIM/Akonadi bugs currently as the 18.04 I am using
is just very old and a lot of even smaller issues may be fixed already.

Please understand that I have other priorities than to guide you through
the process of digging out what may have caused it. Akonadi still
appears complex to me and while I understand quite some of that I do not
claim I have the full picture. But anyway, there are other things that
are more important to me right now. Thus in my recent mails I gave as
much pointers as I could and you can see whether you can go from there.

If you have any more specific question during the process I may decide to
take the time to provide a quick answer.

Thanks,

I've found (as have others) that filtering the Inbox into many
sub-folders seems to randomly cause dupicate emails to occassionally
appear.

However, the Kmail 5.11.0 here on Mageia-7 is otherwise quite steady.

The problem here isn't to do with filtering - though I know you're right that
it often is - but with the content of some data field(s) causing malfunction
in the code. Or so it seems.

  Any particular data field?

Well, of course that's the $64,000 question, isn't it? I'm about to start
exploring ways of tackling the problem from ground zero.
