sftp chroot not working

Hi,

I have configured and installed openssh-4.5p1-chroot on my aix server
5.3-05.

I am able to chroot during ssh connections but when trying to chroot an
sftp connection I am getting the error below:

Any ideas?, I have modified the session.c file, reconfigure and
re-install without any luck. (regular sftp users are not being affected)
