cover_me breaks passenger standalone

Nobody has claimed this yet.

I'm not really sure what's going on here, but I can run my app just fine with webrick. However, when I try to run it using passenger standalone (my preferred server), I get the following stacktrace which appears to be a conflict between passenger and configatron. I'm happy to assist with any further debugging of this issue if you can point me in the right direction. Here's the stacktrace:

Reproduce the difference between WEBrick and Passenger standalone, then trace loading from config.ru through config/application.rb into cover_me.rb and cover_me/config.rb. Inspect the set_defaults path around the reported Configatron error. Done means the application starts under Passenger standalone without this exception while cover_me remains loaded.
