I can confirm that after downgrading these packages
samba samba-common samba-common-bin libwbclient0
smbclient samba-tools
to version 2:3.6.6-6+deb7u7 and then upgrading with
apt-get -t santiago-wheezy install samba samba-common \
samba-common-bin libwbclient0 smbclient samba-tools
the system continued to work without issue; it remained joined to
the domain and users could connect as normal.
Note that this system was not running winbind, it was not installed.
