Details:

When neon is used with resent gnutls version it segfaults when it is used by
subversion to checkout some https repositories. [1,2]

error was in code sample:

    gnutls_x509_crt dest;
    
    if (gnutls_x509_crt_init(&dest) != 0) {
        return NULL;
    }

I tried to find out when this behavior is introduced and find out that it's a
commit: 

  50f0068ae327abce4f648cfb12132b0254f9afa8 [3]

And problem still persist in current gnutls versions.

How to reproduce:
1). install gnutls
2). install neon with gnutls support
3). install subversion
4). try to checkout svn repo (e.g.
https://crossfire.svn.sourceforge.net/svnroot/crossfire)

Libraries and programs:

1). gnutls >= 2.99.4
2). neon-0.29.6
3). subversion 1.7.7
