Once upon a time, it was possible to drag and drop a mail to the korganizer icon. Then, an event was created and the mail's subject was used as title, the mail's body as description of the event. Then, this nice feature was broken.

Some version later, it was at least possible to create a event, then, to drag and drop the mail to the event's attachment field and thereby create a link between mail and event. However, this feature is now broken, too.

Currently, there seems to exist no way to link events and mails.

Reproducible: Always

Steps to Reproduce:
1. Start Kontact. Switch to KMail within Kontact.

2. Drag a mail on the Korganizer icon on the sidebar.

Actual Results:  
A new event is created. The title of the event is something like

"akonadi:?item=50338&type=message%2Frfc822"

which is utter meaningless to the user. Allt the other fields of the event are empty. It is by no means possible to link the mail to the event. Only file attachments are supported.

Expected Results:  
The event created should have the mail's subject as title and the mail's body as description. Attachments to the mail should also be linked from the event. Additionally, it should be possible to link multiple mails to an event by dragging and dropping them to the event's attachment field.

Not sure whether to file this as bug, but it seems to be a repeated regression.
