And the way we can figure that out is with an error message.

I'm surprised that programmers still do this:

"It worked in rails 3.1/1.9.2 but fails to work in 2.3.4/1.8.7."

WTF does "worked" and "fails to work" mean in this context? Does it crash? (If 
so, is there a stacktrace?) Does it do something other than what you expect? 
Does it cause a unit test to fail? etc etc...
