I have occasionally had problems with the debugger statement at the end of a method with it apparently dropping out of the method before breaking, so that variables are no longer accessible. Add an extra line after the debugger statement (i=0 for example) to give it something to break on. On a separate issue, looking at the message you get, are you using ruby 1.9.1? If so then upgrade to 1.9.2 or go back to 1.8.7, ruby 1.9.1 does not work reliably with rails. This may have nothing to do with your problem. I note that you still have not answered my question (unless I missed it), have you any validations on the Storage model?
