Stack level too deep for in lib/amqp/spec.rb:101

[ajsharp]

This occurs when running rspec on a rails project with bundler 0.9.9. We are not actually requiring amqp directly -- it is a gem dependency of minion.

I had this same problem running a Rails app with amqp 0.6.7 via autotest (part of ZenTest).

I was able to resolve it by NOT loading the ZenTest gem in the Rails app being tested. Only the autotest parent process needs that; the Rails app being tested doesn't need ZenTest.

If this doesn't describe your exact situation, then you can still do what I did to try and track it down: just try commenting out gem dependencies in config/environment.rb or Gemfile (or however you're expressing your app's gem requirements) until the amqp gem works, to find out what the conflicting gem is.

It doesn't sound like an actual AMQP bug.
