19133	Possible regression in admin user editor	Daniel Swarbrick	nobody	"Commit c433fcb3fb34fccd69782979f0e7cd5f2d4a4893 seems to have caused a regression in at least two existing projects of mine. I zeroed in on this particular commit after doing a git bisect.

The problem can be triggered by simply opening the admin site, editing any user, and click Save without changing any fields.

The following traceback is thrown:
