That looks like a bug in swift3; something is expecting a callable 
object, but what it's getting is a generator, which is not callable.

You should use the transaction ID to figure out what kind of request is 
triggering the failure, and then go report a bug at 
https://github.com/fujita/swift3/.

Note that swift3 is not part of OpenStack Swift, so please report any 
bugs on Github and not in Launchpad.
