Bug 322703

Since the update to 4.11 RC 1 mails get added to akonadi again and again.
I have a local maildir resource and I am using pop3 accounts. Since 4.11 RC1 mails in most of my local folders are displayed several times in kmail and one finds them also several times in the parttable. And the number is increasing
Clearing the akoandi cache via akonadiconsole helps until all the content of the folder is added again to akonadi.
I did not jet find a pattern, which of my local folders are effected, as I have folders without duplictates and others which contain every message 11 times.

Since bug did not happen for me with 4.11 beta. Please tell me if there a logs, etc. I can provide   to help. Comment 1 in bug 322126 sounds similar, so maybe this one is a duplicate. But this bug is so grave IMHO, so I decided to make a new report just in case these are actual differnt bugs.

Reproducible: Always

Steps to Reproduce:
1. Run kmail
2. Wait
3. Get the message 10345 new mails for kde; 5000 new mails for....
4. You still have 10345 mails in your .local/share/local-mail/..../kde folder but 20690 mails are displayed for this folder in kmail/akonadiconsole
5.The next 10345 mails are added to this folder in akonadi
