Comment 9 for bug 1308657

It turns out that samba-libs contains a shared library that depends on the libpytalloc-util.so.2 library from python-talloc:

$ ldd /usr/lib/x86_64-linux-gnu/samba/libsamba_python.so.0 | grep libpytalloc-util
 libpytalloc-util.so.2 => /usr/lib/x86_64-linux-gnu/libpytalloc-util.so.2 (0x00007f0603701000)

So we can either:
  - move /usr/lib/x86_64-linux-gnu/samba/libsamba_python.so.0 to samba-python
  - move libpytalloc-util.so.2 to libtalloc2
to get libsmbclient upgradable.
