No, and unfortunately this was not properly documented.
The change was in gnutls_0_2_11 where gnutls_global_init()
was modified to no longer call signal(), to ignore SIGPIPE.

I believe it is better that way, because gnutls does not
cope with the transport layer directly, and in some applications
blocking this signal might break things. 

In brief the current behaviour of gnutls is not to cope with signals
at all.
