Fixed in #3110

[chevdor]

@rphmeier Are you sure? what you reference has been merged (10) hours ago. I pulled a few minutes ago and I see the issue.

[gavofyork]

are you certain you rebuilt and are running the latest version? could you post parity --version?

[chevdor]

I am on master:
Parity/v1.4.0-unstable-**3cb355d**-20161103/x86_64-macos/rustc1.12.1

[rphmeier]

@chevdor my mistake, I thought it was the same error.
