Your code could easily get stuck in a loop in the error handler...

ie: any unhandled exception goes to Application_Error, including any
exceptions thrown in Application_Error.

I've been bitten by this a few times. ;) Best thing to do, is check for
nulls where you can and put a try/catch around everything. An error in
the error handler is pretty pointless.
