[Evolution] filter on mailing list bug?

[Mertens Bram <bram-mertens linux be>]

Hi,

I have defined a filter that moves all message from the ximian mailing
lists that contain attachments to a certain folder, however this filter
also causes some messages in my inbox that were not sent to the mailing
list but do contain attachments to be moved to that folder.

I want to make sure I'm not doing something wrong here before submitting
this as a bug.  The filter is defined as follows:
Execute action if all criteria are met
Mailing list contains @ximian.com
Attachments exist

Move to folder
stop processing

(I created the filter and the rules from the filter window, I did not
use the "create rule from message" option.

I checked the source of the messages but the word ximian is nowhere in
the headers or the body.

Is this filter invalid or is this a bug? If it is a bug what should I
include in the bug-report? The message is quite big because of the
attachment...

TIA
