rails_panel/meta_request blocks better_errors and binding_of_caller from displaying

[JezC]

Hi, I'm seeing that BetterErrors and more important BindingOfCaller, are not having their right hand panels when I have the Chrome JS inspector open, and the gem 'meta_request' present and RailsPanel installed.

Latest Chrome 36.0.1985.126 (ChromeBook)
RailsPanel 0.2.1
meta_requests 0.3.3
binding_of_caller 0.7.2
better_errors 1.1.0
Ruby 1.9.3 p547
Rails 4.1.4

The test case that I'm using is to deny access to the database in a freshly installed Rails 4.1.4. Definitely raises an error, that one. ;)

If I have all enabled and the Developer Tools open, then I can't see the right panels and the REPL.

If I comment out meta_request - it works

If I close the Developer Tools pane - it works

When Chrome Dev Tools is open, with RailsPanel, and meta_request, then BetterErrors and BindingOfCaller don't appear.

I haven't tried removing RailsPanel itself... Because the issue appears to be tied to interaction with meta_request. No meta_request, no problem with RailsPanel (other than no data, of course).

Happy to push a repo of my test case - https://github.com/JezC/RailsPanelBlocksBetterErrors. I have a basic Rails 4.1.4 project, Ruby 1.9.3p547, running on Nitrous. I know one shouldn't run BetterErrors on public facing servers, so I use a passworded SSL connection for development, and I've opened up the ports on that assumption...

My basic holy trinity of better_errors/binding_of_caller/railspanel is wonderful for developing and investigating. What else can I do to help resolve this?

Thanks for the demo of the issue. I'll investigate.
