Tag this build unusable as credentials menu is empty after Jenkins upgrade

[Sarah Woodall]

Has anyone else seen this problem?

I've just upgraded my Jenkins installation from 1.625.3 to 1.642.3, and
upgraded all my installed plugins to match. Everything seems fine except
that I can no longer use "Tag this build" in jobs that checked out their
sources from svn. The "Credentials for tagging" dropdown is empty.

The credentials are still present in the system (I can see them in the
list via the "credentials" link), and they are working in other respects
(for example, jobs are checking out their sources correctly, and the
svn-tag plugin is still correctly creating and deleting
"last-successful" tags for jobs where I've configured it to do that).

I've tried creating new credentials, but those don't show up in the list
either.

I've tried downgrading the Subversion plugin from 2.5.7 to 2.5.4 and
restarting Jenkins, but that didn't alter the behaviour.

I can't find anything recent in the Jenkins JIRA that seems to be
relevant. I would have thought this would affect many users, though, so
am rather puzzled why there is no report of it.
