Does setting:

        interfaces = virbr0:0 lo 
        bind interfaces only = yes

help?

Also, does reverting (with 'git revert HASH', where HASH is the commit
id your bisect identified) help?

Finally, can you run Samba under valgrind again?  The error you show
above doesn't seem quite right in the context, and I want to be sure we
are not chasing an unrelated issue.

Thanks,

Andrew Bartlett
