Evolution delays GNOME session quit

[Takkat]

Logging out of a Unity session while Evolution is running blocks log out for approx. a minute. There is no windows decoration, therefore manual closure of Evolution is not possible. Killing the running Evolution process from TTY will lead to an immediate log out.

How to reproduce:
Login to a session to start Evolution.
Wait until there is no more activity in Evolution (that may block application termination).
Log out from the session by me-menu or from terminal `gnome-session-quit --logout'

What is expected:
Evolution should terminate and the login screen should be displayed.

What happens instead:
The windows decoration disappears on all open windows. No launcher or panel, mouse and keyboard are unresponsive.
After 1 minute Evolution quits and the login screen appears.

This is stock Evolution 3.10.4-0ubuntu2 from 14.04.1 LTS (am64 3.13.0-39-generic) but was present in 12.04 and still is in 14.10 (the latter with intact windows decoration however).
