I'd end up reading the documentation and understanding why I was using the library incorrectly. Failing that, I'd go look at how the library was implemented.
There's a distinct difference between looking at something when it's broken for the sake of fixing it and implementing every library on your own because you don't want to use the abstractions created by the programmers who came before you.
