Thank you.  The first three crashes are in a different location than
previously, while the fourth appears to be the same crash.

My hunch is roughly the same as before:  the version of OpenSSL (or the GnuTLS
OpenSSL compatibility library) on your system fails if
SSL_CTX_set_default_verify_paths is called twice.  Without the earlier patch,
it would be called every time a new SSL connection is made.  With it, it's
still possible under certain race conditions for it to be called twice, if two
threads are attempting SSL connections at nearly the same time.

Shortly I'll upload a slightly more careful version of this patch and ask you
to try it instead.
