show_error bug?

[eluser]Unknown[/eluser]
I found issues trying to get this to work as well. I used this example to start: http://www.outofrepose.com/2010/02/17/ex...ons-class/

Two things:
1. JayKae is right, the two signatures are different which adds to confusion for someone not well versed in CI but its manageable.
2. MY_Exceptions.php should be in core and not libraries. (or whatever you prefix your custom class files with).
