This patch does not fix the issue completely.

To re-produce:

1. set View > Attachments to Icons

2. send an email with a large attachment to your imap (not dimap) account

3. click on the email in the message list, kmail shows "loading" in the 
preview pane

4. press DEL to move it to the _local_ trash while it is still loading

5. select a few other read and unread emails and press DEL, kmail will only 
mark them as deleted but the "loading" is still visible in the preview pane 
and no message was removed from the message list yet. (your internet 
connection must be that slow)

6. open the NetworkManagement plasmoid and click on the checkbox "enable 
network", i.e. the one above the "enable wireless network" if you have wifi. 
This must happen before the first email gets removed from the message list.

7. the network will be disabled and kmail/the filter agent will move all 
messages you selected for deletion instantly – without content.

The patch did work though in case the internet connection did not break down 
and kmail/akonadi could finish the download. This lead to mail loss before.
