If you want to pinpoint where the exceptions are occurring, you can select the Debug->Exceptions menu item, and in the dialog that appears, check the first checkbox for "Common Language Runtime Exceptions". This will make the debugger break as soon as an exception occurs instead of only breaking on unhandled exceptions.

This is also one reason why it is generally a bad idea to catch generic exceptions unless you are clearly logging the information caught.
