I don't quite see how this could possibly be caused by gnus. Isn't this
rather a gnutls-cli issue or am I missing something?

It looks like it is caused by gnutls-cli.

However, I explicitly setting tls-program to ("openssl s_client -connect
%h:%p -no_ssl2") but then the following message is displayed in echo
area FOREVER:

  Retrieving message 1 of 1 from pop.gmail.com...

I have to type "C-g" to free Emacs from freeze.

It looks like this is a bug in GNUTLS.

I spoke too soon. After upgrading Gnutls to 1.6.3 this problem still
occurs. It looks like a bug in tls.el.

Does (setq tls-process-connection-type t) help, when you use OpenSSL?

When you use gnutls-cli, it looks like a problem with pop.gmail.com, I
got the same problem.

After setting this to t and using openssl, it doesn't retrieve any new
emails. I tried to "M-g" on the group 5 times and Gnus always says no new
email. But as soon as i set it to nil, I can see there is one new email.

which version of gnutls-cli are you using?

The latest, 2.1.1.  I don't rule out a problem with GnuTLS, but at least
pop.gmail.com doesn't terminate the TLS connection according to the
protocol spec so there is at least one problem with pop.gmail.com.

I wonder if someone could look at this bug. Gnus can not reliably
retrieve emails from pop server.
