kde4-runtime, samba3, and talloc

[Ludwig]

I gather that kde4-runtime's dependency on samba3 is a new thing with the most
recent update, because I have kde4-runtime already installed without samba3 but
the update insists on trying to install it. 

Trouble is, samba3 conflicts with talloc, which notmuch depends on. Is the
solution here to allow the notmuch port to accept samba3 as a provider of
talloc, or to allow the kde4-runtime port to accept talloc as an alternative to
samba3? 

Thanks,
Ludwig
