[Evolution] Problem with Evolution 2.22.1 and appointment invitations

[Artur Mücke <muecke tyntec biz>]

Hi folks, 

I have a problem with Evolution inviting people for a meeting by e-mail.
First of all, here is some information about my sytem.

OS: Ubuntu (Hardy Heron)
Evolution 2.22.1, installed from the official Ubuntu repository

My problem is, that people who are invited by me, don't get a proper
invitation E-Mail like they are used to. 
Normally the invitees should see my invitation e-mail ïwith check boxes
in their client, which they can use to Accept, Decline my invitation.
This is how it works for example with Outlook. 

Unfortunately my invitation e-mails do arrive in plain text without any
functionality in them. ïEspecially Outlook users are complaining about
my invitations. :-/ (Outlook 2003 SP3)

An according e-mail looks like that:

I investigated it a bit deeper and figured out that the same problem
occurs when I am using Ubuntu Gutsy with Evolution 2.12.1. 
Funnily enough it works with Evolution 2.6.1 in Ubuntu Dapper Drake. 

Does anyone have a clue what the problem is?

Cheers,

Artur
