i was on master branch when this occurred. removing dep from my $GOBIN and checkout out tag v0.4.1 and installing that version seemed to work as expected.

Hmm, that case shouldn't be reachable (but obviously it is). i'll get it figured out and fixed up. Thanks!

[sdboyer]

Actually, if you could provide repro steps, it'd be helpful!

[sdboyer]

Figured out the problem! All taken care of now.
