[scponly] segfault when trying to connect

[Tim Donnelly]

Hello list,

I recently installed scponly 4.6 on a OpenSuSE 10.1 server.  scponly was
configured with the following options:

./configure --enable-chrooted-binary --enable-sftp-logging-compat
--with-sftp-server=/usr/lib64/ssh/

I edited the /etc/shells directory as directed on the wiki to use scponlyc
and ran the make jail command to build the chroot jail.

When I attempt to connect to the server using the sftp command I get the
following output in the messages file:

I have ran traces, but to be honest they don't make any sense to me.  I have
posted them at http://www.coalliance.org/public if anyone would care to take
a look at them.

I appreciate any help.
