Comment 4 for bug 1072864

Update again: recently (as in: last week or so) the workaround stopped working. Whenever I accept an invitation, the confirmation that is sent out contains both my correct email address and the self generated (??). This last one is both not correct and not wanted since I accepted this invitation for my private calendar only. It was sent to the associated email address only.

cheers
Tom
