  I'm getting same error, also in initializer ( seems that's initializers issue ), but in rails3.0.beta2!

  Looks like this is not an issue with ruby 1.8.7. I am not able to produce this error with ruby 1.8.7 and rails edge.

  ruby 1.8.7 (2010-01-10 patchlevel 249) [i686-darwin10.3.0]

  I can confirm that I get this problem with both ruby 1.8.7 and 1.9.1 on Windows 7 64bit.
  I first noticed it in the rails console after reloading to see my model changes.
