That seems more like it's bug 1161501 now. If the very first refresh fails,
there's no delay, so it immediately tries again and fails. This means the limit
for allowed silent failures is already met, so the next attempt causes an error
to appear. Might be fixable by just adding a minimum time between attempts.
