Comment 9 for bug 722875

I suspect this is the same as bug 773908 https://bugs.launchpad.net/ubuntu/+source/evolution/+bug/773908. No resolution, but it seems that if you start Evolution with the gnome proxy settings set to Direct Connect, then change the proxy settings back after Evolution starts, it continues to work and the apps that need the prosy setting work as well. This has worked for me. Since I run Evolution 24/7, the only time I need to play this trick on Evolution is after booting. Hopes this helps.
