I’m in the middle of upgrading an application to rails 2.0.2 from  
1.2.5 and on startup I see this message printed out:  
#\<NoMethodError: undefined method `configuration’ for #\<String:  
0x1145040\>\>  
After some hacking I’ve figured out it emanates from plugin.rb in  
railties (railties/lib/rails/plugin.rb) in the following block:

def evaluate\_init\_rb(initializer)  
if has\_init\_file?  
silence\_warnings do  
# Allow plugins to reference the current configuration  
object  
config = initializer.configuration

```
         eval(IO.read(init_path), binding, init_path)
       end
     end
  end

```

In the instances I have seen the failure occur, initializer is a  
string that is the path to an init.rb file inside a plugin.

Has anyone seen this? Is it harmless? Is it because of some plugins  
not doing the right thing for rails 2?

thanks
