Additional info: Mr. Pete Zaitcev (of Redhat) has already produced a patch for this issue based upon some prior conversation on #openstack-swift IRC:

Comment 1 Pete Zaitcev 2014-08-05 21:11:19 UTC 
The practice of creating objects with a trailing slash is documented in
OpenStack Object Storage API v1 Reference, section 1. "Object Storage
API concepts and features", clause "Pseudo-hierarchical folders and
directories".

http://docs.openstack.org/api/openstack-object-storage/1.0/content/pseudo-hierarchical-folders-directories.html
Comment 2 Pete Zaitcev 2014-09-09 18:52:48 UTC 
The fix is merged upstream on August 17 as commit
3d56b65c898d7997819f2627a2fb722bd0c33b69.
Additionally, a fix-up corrected tests as commit
309437bb5255a2205337fb951fc3c6836cfdaabf.

There was no release since 2.2.0 in July. If we go cherry-pick
for this, I recommend we only pick the main commit for simplicity.
