Hey Loïc, I applied all your patches to both Tinymail's trunk and the
devel/pvanhoof/bs branch.

For future you can also post patches to our mailing list (if mailman
blocks you because you're not subscribed, I'll add your From to the
auto-accept list).

This is correct. Tinymail uses NSS for its SSL implementation in 

	libtinymail-camel/camel-lite/camel/configure.ac

You can opt for using OpenSSL in stead by passing --with-ssl=openssl to
Tinymail's configure options. Doing that will make Tinymail not depend
on NSS/NSPR, but instead on OpenSSL.

We have a very interesting bug in NSS/NSPR by the way. The coredump of
our tester regretfully revealed few information. Other than these
stacktraces.

The problem seems to be related to PR_CreatePipe. I looked at the
location where that mutex (that seems to be NULL) is set. It looks like
it's set in a pthread_key_create
