Can't set custom http-proxy on GnuPG-settings, lost after restart

I'm using Polipo as an HTTP-proxy over Tor, which is listening on port 8123. If I'm searching the keyserver for keys with Enigmail, it does not work, because the default setting is "http-proxy=http://127.0.0.1:8118". If I'm changing this setting to "http-proxy=http://127.0.0.1:8123", it works, but is reset after the restart of Icedove.

Please add the opportunity on the settings-menu to permanently set GnuPG-HTTP-proxy.

TorBirdy-Version: 0.1.2
