glibc detected invalid free in ssl_disconnect when using NSS

[pp@…]

When running 3.2 from Fedora 18 (msn + facebook xmpp with openid connected) I often get a bitlbee crash.

( ​https://bugzilla.redhat.com/show_bug.cgi?format=multiple&id=918816 seems to be downstream bug, 3.0.5 works fine here too). Quickly looking at the code, smells like a ssl_nss.c issue that wouldn't happen with say openssl.
