World's longest stack trace?

I really love all of the useful libraries that have grown out of the open source movement in the last couple of decades. It really makes assembling powerful applications out of freely available components very easy (as long as you use robust components!), but when the stack gets big and things go wrong it's kind of worrying when you see stack trace this long:
