User-Agent:       Mozilla/5.0 (X11; Linux i686; rv:2.0.1) Gecko/20100101 Firefox/4.0.1
Build Identifier: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.2.9) Gecko/20100827 Red Hat/3.1.3-1.el6 Thunderbird/3.1.3

After configuring a directory server in Thunderbird's Address Book, all searches using this directory server generate network traffic directly from the machine on which Thunderbird is running to the directory server bypassing the configured proxy (socks5 in my case). This is easily verified by monitoring your outgoing traffic while conducting a search on the directory server.

Reproducible: Always

Steps to Reproduce:
1. Configure Thunderbird to use a socks5 proxy, and set network.proxy.socks_remote_dns to true in the config editor.
2. Configure a directory server in Thunderbird's Address Book
3. Start wireshark on the machine on which Thunderbird is running.
4. Select the directory server in the Address Book's main window and enter a search term in the search box.
5. Watch wireshark as both the DNS request for the directory server and the subsequent search traffic bypass the configured proxy.

Actual Results:  
Both the DNS request for the directory server and the subsequent search traffic bypass the proxy configured in Thunderbird's network settings.

Expected Results:  
That both the DNS request (provided that the network.proxy.socks_remote_dns option is set) and the subsequent network traffic generated by the Address Book when searching through a directory server would use the proxy settings configured in Thunderbird's network settings.
