Running Test Suite causes Bus Error with yard

[mvbehr]

Hi,
I am trying to contribute to the project.
When I run the tests I get the following Bus Error with yard. I tried it out with ruby 1.9.3 and ruby 1.9.2.
I can avoid the issue by commenting out the yard-gem in the Gemfile and the yard.rake-file.
Running on Mac OS X V 10.7.3

$ rake test
/Users/mb/.rvm/gems/ruby-1.9.2-p290@active_admin/gems/yard-0.7.5/lib/yard.rb:38: [BUG] Bus Error
ruby 1.9.2p290 (2011-07-09 revision 32553) [x86_64-darwin11.2.0]

That's a ruby interpreter bug.
