Strange pkg messages

[Frank Seltzer]

Since upgrading to pkg 1.3.0 I have been getting lots of these:

pkg: invalid chunk added
and
pkg-static: invalid chunk added

I use portupgrade to install and upgrade ports and I get anywhere from a 
dozen or so to hundreds of these messages every port I update. I even get 
a few of them doing portversion -vL =.

Is this a known problem or did I fat-finger something?
