[Mono-list] procedures causing app to exit

[Jonathan Pobst]

In any gtk# application you will probably want to attach to the 
GLib.ExceptionManager.UnhandledException event so you can handle 
unhandled exceptions instead of the app just exiting.

When you handle that, you can print out the error to the console, which 
may help you find the problem.
