I doubt that this is handled by the new default behavior in 1.4.4. Don't know that it's truly necessary if the network plugin is the only plugin using gcrypt. Here's a patch that works for me with 1.4.1. I followed an example for pthread initialization and initialized gcry to 32k, only since that's apparently the default that's used in 1.4.3. I did it in network.c's module_register function. Kind of an abuse, I know.
