I've already applied this patch as part of a previous discussion on
the list, so it's in the latest version of the Erlang client. The
Erlang client has been migrated from monotone to hg, we are just
waiting on some infrastructure changes to go through to make the
Erlang client public again. Let me know if you want me to send you a
zipped image of the latest version for the meantime.

HTH,
