Ok I found bug.
Fixed soon.
Comment 2 Laurent Montel 2015-03-12 06:48:53 UTC 
The problem was not that you read email, just that favorite model doesn't exist for you.

Comment 4 Laurent Montel 2015-03-12 06:58:41 UTC 
if you don't want to have this crash until 4.16.7 add favorite it will not crash.
It crashs because favorite is not show in kmail and a signal try to access to it.
