Comment (by dx):

 Attached test case server. Not the greatest code but does the job.
 Probably requires python2 instead of python3. Copying instructions here:

 {{{
 # test case irc server for pidgin bug #12562. usage:
 #
 #   openssl req -batch -nodes -x509 -newkey rsa:2048 -keyout server.key
 -out server.pem
 #   python server.py
 #   python server.py 2
 #
 # the arg is the number of 512-byte filler messages. 2 is enough to break
 it.
 }}}

 Quoting myself from the dev channel:

 > <dx> i think this bug is a problem that applies to all prpls that use
 ssl, not just irc
 >
 > <dx> or maybe irc just happens to be the one protocol with the lowest
 buffer size, 1024
 >
 > <dx> i can't find anything equivalent to this
 https://github.com/bitlbee/bitlbee/blob/0db6618/lib/ssl_gnutls.c#L425-L443
 >
 > <dx> or this
 https://github.com/bitlbee/bitlbee/blob/0db6618/lib/ssl_nss.c#L287-L296
 >
 > <dx> maybe recv_cb in sslconn.c should keep calling the callback while
 that condition is true
 >
 > <dx> this probably means adding another ssl op though
