Does action_profiler work on edge?

Rails
#1

I have some slow actions that I wanted to see which calls in them were
eating all the rendering time. I found the action_profiler gem from:
http://rails-analyzer.rubyforge.org/

The problem is the gem doesn’t work. It seems to be an issue with edge
since it runs fine on a virgin app running on the rails gems.

It seems to be loading some rails files from the gems, and some from the
vendor/rails directory of my app, as seen in the below trace.

Any ideas on how to make action_profiler work on edge?

Oops, forgot the error trace:
