Comment 10 for bug 460483

I see, thanks for the answer. I guess the situation is quite complicated, then.
A clean solution will probably require patching Evolution directly and it is
well-known that close-to-tray is a feature that goes directly against upstream's
wishes, as it supposedbly violates the Gnome HIG.

Going against upstream's wishes is a bad move, and an unmaintanable
decision in the long term.
