Version:           2.0.89 (using KDE 4.6.0) 
OS:                Linux

I set filters to check address and copy message to folder. (@facebookmail.com -> to notification folder, for example)
I want that kmail mark original mail as read, and leave only copied message as unread.

Unfortunately setting filters as:
*Copy into folder
*Mark as Read.
Resulting in conflict. Message copied to folder but marked as unread.
Also popup is shown with error message:

Reproducible: Always

Steps to Reproduce:
Set filters to:
*Copy into folder
*Mark as Read.

Actual Results:  
Error mesage and original mesage marked as unread.

Expected Results:  
Original mesage marked as read.
