I’m using the One-click 1.8.7rc2 Ruby Windows installer, everything has been working fine up till now, when i want to start getting into testing, i got this error, any reason why?

I had the same error running my tests. It was working fine then stopped working with the above error. Unfortunately, the trace is not real helpful because the error was occurring in environment.rb … template\_handlers.rb … erb.rb. Rather than debug Rails or Ruby I went through a process of elimination to find what file was causing the issue. I found a .jpg file in one of my view folders that if removed allowed the test to complete properly. Per where the error occurring in template\_handlers, while I don’t know why it puked on this file, it did relate to a view folder. I don’t recall any documentation restricting .jpg files from view folders but maybe I missed something. I hope this helps.
