Whenever you enter a folder that you haven't been for some time, Akonadi floods the system bus with signals. Please consider throttling the signals sent on update progress (at most 1 every 5 seconds).

You also don't need to send from *both* the imap resource and from the Akonadi Control process.

Here's a log from dbus-monitor of when I clicked on my Inbox. Owner mapping:

Reproducible: Sometimes

Steps to Reproduce:
1. Open KMail
2. Find a folder you haven't been in for a while
3. Click it

Actual Results:  
200 signals are sent in the space of a second or less, one per percentual point in the progress.

Expected Results:  
No more than 1 signal every 5 seconds is emitted.
