Thats exactly my case! GnuTLS 2.8.6 on Ubuntu 10.04. Thanks a lot for the prompt reply. Though I'm not at my machine right now, but I'll surely do what you've said and let you know if I face any other problems. But yes, your observations are exactly correct regarding the client and server code in 2.x and 3.x!
I hadn't expected an early reply on Superbowl Sunday! Anyways, thanks a lot.

This sounds like the same problem I ran into recently. I saw the exact same behavior when I tried compiling the current version of the example programs against the GnuTLS libraries that came with my operating system. (GnuTLS 2.8.5 on Ubuntu 10.04.)
I'm assuming my issue (and therefore yours) is that I was running example code that was meant for GnuTLS 3.x against an installed library that was GnuTLS 2.x. (And, presumably the change in major version indicates an incompatibility, although unfortunately in this case it's a rather subtle one.)
When I installed the examples that were meant for the version of GnuTLS I was actually using (by installing the "gnutls-doc" package on Ubuntu, which put the example source code in /usr/share/doc/gnutls-doc/examples), and compiled them, it worked fine.
(Presumably it would also work to build the latest GnuTLS from source, and then use the latest example code, but that's not the approach I went with, because I wanted to write code that would work with Ubuntu's binary packages.)
In particular, the 3.x example code has the while loop you mentioned, while the 2.x example code does not have the while loop.
(The example anonymous server is ex-anon-serv.c in both the 2.x and 3.x examples, but the anonymous client is called ex-client1.c in 2.x, while it's called ex-anon-client.c in 3.x.)
I hope that helps,

I am part of a team at University of California, Irvine who are trying our hand at GNUTLS. We installed the package and all its dependencies. But when trying with the example code given in the documentation, it throws up an error. The details are:
I tried running the server and client with anonymous authentication. The exact error that it gives is:
