handshake issue with gnutls 3.0.3

[frank.krout at eurorscg.com]

Anyone run into this. I'm new to GNUTLS and having an issue in 
multi-threaded app.

Via application mutex's, I've serialized access to GNUTLS_HANDSHAKE in 
order just to get a successful handshake... and am getting this:

Info: Initializing GNUTLS


The gnutls-cli app runs fine, built in same environment and does not use 
gnutls_global_set_mutex.
Since it does work,  I've modeled my code largely after ( src/cli.c ), not 
using set_mutex either.
I realize it's a single thread, that is why I serialized the handshake in 
my app.

So the random function works fine for gnutls-cli, I don't get what's going 
on.

Hoping this is "low hanging fruit" for the community.... otherwise I just 
have a wild pointer somewhere...
I've read through the docs and mailing list, so unless I missed 
something...

Thanks..
