Hi.

I found the bug in bind conflict resolve path, when bundle was not
unlocked after conflict was detected, attached patch should fix it.

If testing will reveal some new problems I will return with the fix
then. Please apply or queue for the appropriate tree.

Applied, thanks Evgeniy.

If I end up rebasing the net-next tree before publishing, I'll
integrate this fix into the original commit.
