Evolution doesn't recognize ICS mail-attachments

[Christian Menzel]

Hello list!

I just switched to Hardy from Fedora 8.
So far I'm quite happy with Ubuntu, but there is one thing that I miss.
The Evolution in Fedora can handle ICS calendar attachments and shows
a dialog in which you can accept or decline an invitation.
Evolution in Hardy just shows the text of the invitation but does not
even show there is an ICS attachment.
At the moment I save the message and open it with Mutt to save the
attachment which I then import into Evolution.
Is the an additional plugin I have to install or is this a known
behavior of Evolution in Ubuntu?

Regards
Chris
