terms panel does not handle entries with -

[KlavsKlavsen]

When setting up a terms panel on my 'hosts' field, I get this:
p (25026465) varnish01 (12266997) varnish02 (12216775) yspro (525439) batch01 (525439) voduzi (73440) t (73440) pre (73440) varnish03 (17254) Missing field (177437) Other values (0)
TypeError: Cannot read property 'length' of undefined

where varnish01 and varnish02 is actually: p-varnish01 and p-varnish02 (and also shown as that in the host field - in the result set).

And then there's that TypeError.. I don't know what that is - or how to debug further?

I'm running kibana from github as of 28/10.

See #648, this is expected behaviour, except for TypeError.

Thanks for the hint. I'll look into the mapping.
How do I debug that TypeError?
