[Box Backup] Segmentation fault from bbackupquery (exception Connection TLSHandshakeFailed)

[Ben Bennett]

I am trying to get boxbackup working between two linux machines on the
same lan.  The machines are:
  ayup: (bb server) Redhat FC 6
  thar: (bb client) Gentoo (up to date with stable)

Both are running bb 0.10 (ayup from rpms built of the 0.10 tgz, and
thar running the bb 0.10 ebuild).

I started bbstored on ayup, then ran the following on thar:
# bbackupquery
Box Backup Query Tool v0.10, (c) Ben Summers and contributors
2003-2006
Using configuration file /etc/boxbackup/bbackupd.conf
Connecting to store...
Segmentation fault

The following appears in /var/log/messages on ayup:
Jan 29 09:03:53 ayup bbstored[3524]: Incoming connection from 10.10.100.3 port 52738 (handling in child 16796)
Jan 29 09:03:53 ayup bbstored[16796]: in server child, exception Connection TLSHandshakeFailed (7/30) -- terminating child

This happens every time.  I tried regenerating the keys for the client
and server, and it makes no difference.

To try to narrow this down more, I set ayup up as a client too, and it
works successfully there, I can run bbackupquery and I get the
expected prompt.

In case it helps at all, here is a backtrace from gdb of the
bbackupquery on thar.  Unfortunately I have my system compiled with
-fomit-frame-pointer and I have stripped libaries, so there is not too
much information available.
