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.

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.

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.

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

I hope the following backtrace is of use.
