 A very interesting read! Is this fix being deployed already? I am asking,
 because I am still suffering from it (and I fear, there might be a better
 place to mention this?)

 My system is Ubuntu 14.04 running pidgin 2.10.10. This is what pidgin -d
 gives me:

 (14:29:22) nss: SSL version 3.3 using 128-bit AES-GCM with 128-bit AEAD

 $ cat /etc/*{release,version}

 $ pidgin --version
 Pidgin 2.10.10 (libpurple 2.10.10)

 How can I fix this? Download the source (instead of apt-get...) and
 compile it from there?

 Thank you in advance.
