Comment 4 for bug 777777

This has just been fixed upstream.
Mailing list discussion was here: http://mail.gnome.org/archives/evolution-list/2011-August/msg00084.html
Fix is here: http://git.gnome.org/browse/evolution/commit/?id=d33ed726f9562015b65c27360b02be0dfad7c11b
In general for Evolution bugs, I'd recommend logging it upstream at https://bugzilla.gnome.org/ as that'll get it seen by its developers and fixed faster.
