I can't recreate this. Need someone else to confirm, or check it is still a bug.

I've seen this happen. Is it ok if I take a stab at this?

    Instance overview renders erroneous markup

    Under Instance Detail | Overview | Meta | Key Name an unclosed </em>
    is rendered for an instance launched without an associated key pair.
    This seems to be reproducible using Django 1.6.1 in local devstack.
    The issue seems to be that Django's implementation of the add filter
    has an issue concatenating a string and a function to localize text.
    Since that fails and returns an empty string which subsequently is
    added to the closing </em> tag, the closing tag is the only thing
    that is displayed.

    This fix saves the localized value to a variable which is then used
    in the add filter.
