Especially in an inbox folder of an IMAP account, that was empty before fetching new messages, after reading a message in that folder and deleting that message, often, not always, the messages list becomes empty. Selecting another folder, any, and reselecting the previous folder shows the remaining messages in that folder in the messages list. One message in that folder is marked as read; the one next to the deleted message. This may repeat itself, not always, with the next read/deleted/moved message.

Reproducible: Sometimes

Steps to Reproduce:
1. Start Kontact with IMAP account with originally empty INBOX and fetch several messages.
2. Select one message to read and delete that message, it goes to the waste bin.
3. The messages list becomes empty.
4. Select another folder and reselect the INBOX folder, the remaining messages reappear.


Expected Results:  
The messages list should keep showing the remaining messages.
