OK, filtering IMAP message which stay in the same folder will simply not work with GMail, because of their idiotic duplicate prevention.
Filtering works the following way:

1. KMail copies the IMAP messages to a local folder
2. KMail filters the message in the local folder
3. KMail moves the filtered message from the local folder to the IMAP folder
4. KMail deletes the original message from the IMAP folder

Because GMail prevents duplicate messages, step 3) will fail (although the new message has an additional header). Please complain about this to Google.

The other problem is that filtering stops when encountering such a problem. This is being worked on, but the patch won't make it into 4.1.
