When I accept an invitation I got, kmail correctly sends an email back. Looking into the sent mail folder and clicking on this sent email shows the ics in plain, e.g. starting with: BEGIN:VCALENDAR PRODID:-//K Desktop Environment//NONSGML libkcal 4.3//EN VERSION:2.0 X-KDE-ICAL-IMPLEMENTATION-VERSION:1.0 METHOD:REPLY ... END:VCALENDAR This invitation has been updated by an attendee. Your status for this invitation is Accepted. The <b>Accepted</b> response has been recorded and just below this kmail shows the nicely rendered HTML version. (this is independent of the "view attachments ..." setting) 1) the plain text version is not needed 2) the "bold" <b></b> tags should not be shown on the "button" but it should be really shown in bold text
"1) the plain text version is not needed" I confirm that it's not necessary. But when mailer doesn't have renderer ical support we need to provide a text. But for sure not the plain text version. I will investigate it.
