You could add them to the bug report; arguably they would point to a
way to fix it without tradcpp.  But my real concern is described in
bug 246943, and so far I don't see a clean solution for that.

Does root have a calendar file on your systems?  If so, how do you
handle the multiple emails?  Your input on 246943 would be
interesting.
