[Evolution] Race condition?

[Patrick O'Callaghan <poc usb ve>]

When a new message arrives it often shows up in my Inbox and then
quickly disappears after being grabbed by an input filter and refiled
somewhere else.

This is confusing to say the least, but may also be related to a
phenomenon several people have remarked on: the same message often
appears both in Inbox and in another folder. I mean the *exact same
message*, not a duplicate. I use a Cyrus IMAP server and both "copies"
of the message refer to a single physical file on Cyrus' database (Cyrus
uses Unix links to make the message appear in several folders). This is
not a rare ocurrence; it happens to me regularly several times a day,
and only with Evo (I sometimes use Thunderbird, also with filters, and
it never exhibits this behaviour).

Is this a synchronization problem between several components of Evo? Can
someone fix it?
