Fixed, thanks! I also took out setting it to 0 if it didn't already exist.

It seems that IMP is to blame. Replacing $vEvent_reply->setAttribute('SEQUENCE', $vEvent->getAttribute('SEQUENCE') + 1); in imp/lib/MIME/Viewer/itip.php line 230 with $vEvent_reply->setAttribute('SEQUENCE', $vEvent->getAttribute('SEQUENCE') ); should do the job.

When replying to an invitation in iCal format e.g. from Apple iCal, Kronolith increments the tag SEQUENCE in the reply. This confuses Apple iCal and prevents it from parsing the reply. The field must not be incremented, cf. RFC 2446, para. 2.1.4. When Kronolith itself sends invitations in iCal format, it does not include SEQUENCE tags. Thus, this bug does not affect Kronolith users inviting each other.
