Interesting! I've found the problem, but not the fix. I was store my ActiveRecord errors in the flash as shown below:
flash.now[:errors]= @object.errors This apparently causes problems when you are using PaperClip and there is a validation issue. It may be trying to put the file in the ActiveRecord Errors object. I'm just going to have to change how I do my flash error messages... Thanks!
