OS:                Linux

When I delete new emails from kmail it freezes because of akonadi.
kmail processes uses 100% of cpu in top and here is the backtrace:

Reproducible: Sometimes

Steps to Reproduce:
1. Click on an unread message
2. Delete it


Expected Results:  
kmail should mark the email as read and then delete it.
