I know a Karaoke software written in .NET, that doesn't check
if a list view is empty when trying to select the first
element. It results in a popup message about the Exception and
you can continue from there.

It is a logic error (aka assertion), but being tailored
towards user interfaces, .NET doesn't kill the app.
Heck, if Mono-D closed down on every NPE I wouldn't be using
it any more. ;)
