Comment 2 for bug 1537721

In the bug report, the presence of this zero length object

5b955bce-61ab-4c55-afd9-8bd6012cf1ab-00009

 suggests that the patch

https://github.com/openstack/glance_store/commit/a0572ef672512a8ed7ef203816ec256eafd5f9de may not have been applied.

Can you re-run your reproducer, with the api server in debug mode (it it isn't already) and search for this log entry:

'Not writing zero-length chunk', eg:

 2016-01-25 12:29:23.567 DEBUG glance_store._drivers.swift.store [req-c763b94f-73c5-4577-a27f-bce3fd
 32943f b2e2adda995f4b34880f956fa85e30b0 a03febe481094927a96fe367c15c347b] Not writing zero-length chunk from (pid=26218) add /usr/local/lib/python2.7/dist-packages/glance_store/_drivers/swift/store.py:555

That will confirm whether or not the referenced patch is present.

Thanks.
