Vista 64bit and keyserver upload

I’ve been trying to upload my public key using Enigmail in Thunderbird, and I get “gpgkeys: this keyserver type only supports key retrieval” from each of the servers. Googling for that phrase does indeed find a thread indicating a patch for gpg.exe to fix that behavior was created in March of 2007, but it seems that the current gpg4win still has this bug. Was the patch actually committed, or is there some other problem I may be having?
